Psst, this is a helpful post, I don’t mean to nitpick, but I think you mean something like vocab or total items? WK only has a bit over 2000 kanji total. I just don’t want to mislead them!
No, no you’re right! I was reading my little fuel gage thing wrong and looking at the incomplete kanji so far! Thanks for mentioning that! I honestly thought the number seemed oddly high when I typed it out too, but all logistics go out the window when you hear baby crying! 
Even if you think you screwed up, you’ll eventually find that a year is not that big of a deal. 
I don’t think you’ve screwed up. I mean how much do you know now that you didn’t know a year ago?! A lot. A massive amount. Don’t say you’ve screwed up big time, I don’t think that’s true at all. You’ve learnt masses.
I mean I do say this because I’m pretty much in the same position as you
It’s because I don’t find much time (energy) to sit over a textbook. But now I feel in a really good position to try reading things. Now I don’t have to sweat over all the kanji as well as trying to figure out the grammar as well! That’s got to be a good thing. Imagine going at it with no background at all. You see you’ve not been wasting your time. You’ve been putting in the preparation. You’ve got the rest of your life to read things and improve at Japanese.
Have you tried the tadoku books or Crystal Hunters, or some of the things in this thread?
Have you?
Or have you built a foundation for reading practice?
Because I’m leaning towards the latter. You haven’t screwed up, you’ve just come to the realisation that your knowledge is unbalanced. You know how to fix this - learn more vocab, learn grammar, and read.
You absolutely didn’t screw up big time. You’re learning.
You might feel and think differently, but you haven’t screwed up.
They advertise it as learning all the kanji in one year, but that’s for a select few of people. Most either quit or spend multiple years.
So if you’ve been sticking to it after one year, that is dedication and good work. Don’t stare blindly at the results, look at where you were and how you are now. It’s a bit hard to gauge where you are at that point, but you’ve learned plenty of kanji where you can pick up a beginning grammar textbook and see them back. Keep moving forward, with a small step at it every time and you’ll improve a lot.
My first year of learning Japanese, I did a year of evening classes where we learnt no kanji at all and I wasn’t really confident with katakana by the end of it and when I watched japanese tv I’d be lucky if I understood one word even with the english subtitles on. Seriously, you’re fine.
I’m in the same boat, but spent 12hrs a day for 9 months and barely know what’s going on in anime. If I use japanese subtitles however I get the gist of it.
You’re probably not putting in enough effort.
Just trying to make sure I’m reading this right. No typos?
What typos?
I feel the same way with pronunciation.
All hope is not lost!!
You’re not alone, i started fully dedicated to WaniKani from September 2020 and starting level 4, i’m currently at 44, it’s quite bizarre that i know almost all N2 Kanji and can recognize most of them in lyrics, on the web, still i haven’t touched grammar and it’s noticeable, because i can read but it doesn’t make much sense a lot of the times because of grammar, being a different structure than english/spanish, having chosen to be dedicated to the Krabigator i might take WaniKani a bit lighter and focus more on grammar.
TLDR: I’m the same but at level 44, must balance WaniKani with quite a lot of grammar to get to my kanji reading level (~N2)
Wow level 44 and I see this is your first time posting in the community! Welcome 

Spending 12 hours a day studying for 9 months
Probably a bit more than that, was a cautious estimate. From I wake up to when I fall asleep (usually reading). Much of it is consuming content though.
I started putting into practice my reading only in lvl 11 with nhk easy news
and only recently lvl 33 in WK i started studying grammar with bunpro
I think every study need steps, so when I felt I needed something else, I went that path.
Also I listen to short podcasts (5min tops) every other day.
My next big step would be to read manga all in japanese, but since I confuse kanji all the time, I would mess big time trying to read without yomichan 
I quit learning Japanese for many years entirely if you want to talk about “screwing up big time”.
But here we are now in 2022, and the only way is forward. Time to break out the old Genki 1.
You only “screw up” if you stop…there is no “correct order” to learn something in…if you learn all the kanji you are a step ahead when it comes to other stuff. Yeah reading is always hard in the beginning regardless, but just keep going and plant that tree now. So what that you learned more kanji than grammar…what’s the harm? Might be discouraging if you thought you were going to be able to read right away, but … that probably wasn’t gonna happen anyway… reading in Japanese is gonna take some getting used to, especially for English natives…the grammar is so different. [Book Clubs!! - Absolute Beginner Book Clubs are a great place to start]
If you think you might forget that kanji you learned when you started, yeah you might (and some you will)…but it will be easier to recall if you have to look it up…Don’t worry about the small stuff and press onwards! You’ve have accomplished more than many do when studying Japanese (most people give up!)
You can do it…!!!
I agree totally with him. Now that you’ve realized that your knowledge is skewed, you can improve the areas you’re not familiar with. Try clearing the two Genkis at your own pace and take WaniKani more lightly until you feel properly balanced.
Don’t worry, that’s what I’ve been doing for 2.5 years now. You learn the language even by just trying to translate WK’s example sentences. Sure, I can’t understand spoken Japanese nor can I speak it myself, but at least I understand short comics on Twitter.
