Since you’re a self-proclaimed newbie, I highly recommend you read This Ultimate Guide to Wanikani. It’s written by a previous user who made it to level 60 and shared his insight about what he had learned along the way.
There’s information about how to setup your schedule to be most effective for you, scripts, and just general information about how wanikani functions. I found that having a better grasp of how the system worked really benefitted my progress.
I also want to give you some perspective about language learning. Consider a 5 year old child learning their first language. Do you know how much time that child has spent learning their language by the time they turn 5? Even if we say that the child is only awake for 12 hours a day over that 5 year period, they have still gotten 21,912 hours of input in their entire life. (by input I mean they are hearing the language from the people around them, media, etc.)
Now consider that 5 year old children regularly have trouble expressing themselves, despite all that time.
Now you are an adult (I assume), so you can obviously learn much more quickly than young children can, but the point is that learning a language takes a massive amount of time. At 15 minutes a day, you should expect your progress to be slow. Find a pace that works for you and do your best to be consistent. Wanikani is a marathon, not a sprint!
