You need to slow down. If it helps, I got an adult who wouldn't step up for 2 months (other than day 1, when I took her out of her carrier and placed her on her cage). You have to stop pushing your agenda and move at her pace..Also, don't keep her locked up just because she doesn't like you at the moment. There are innovative ways to get them back in when you cannot touch (do NOT towel unless it's an emergency, as this will make her really mistrust you). Also, if she goes back in her cage on her own, no matter how long you have been waiting DO NOT immediately lock the door or you will cause her to make a connection between going in and getting locked up. Let her go in and out a few times and make sure that more than half of the time, when she goes in, she is not getting the door shut on her.
Build trust....she is going through a lot. You did something to scare her and if she bites, you definitely aren't paying attention to her cues. If she hesitates or runs away STOP.

Many people only wait until they see fear or anger before backing up, but that is REINFORCING/INCREASING the odds of that reaction (as it is the only thing that gets the person to back off). Instead of focusing on "warnings" and fearful body language, do not proceed until you see inviting/open/willing body language. It works. Of course, back off is you see fear/stress or aggression, but the point is, if you wait until you see those signs before backing off, you harm trust each time and become associated with a stress response.
Another tip- your bird is not sexually mature. They are fully sexually mature around 3 years, and you can bet that you will have to really focus on a lot of these things at that time as well. Just like teen humans vs babies, your bird is still a baby. It will most certainly provide greater push-back around sexual maturity because parrots push away from their parents in the wild as well. Be prepared for this. You may feel like you have lost trust again, and that is okay. You may have to go back to basics then again.
**if you are not already --10 hours sleep nightly with a set wak-eup and bed time is ESSENTIAL for proper immune function, mood regulation and hormonal regulation. Disregarding this need is absolutely TERRIBLE for you and your bird. This is true now, but you will see even greater impacts on mood the longer you fail to provide adequate, solid 10 hours on a nightly schedule** If you are moving around outside of the cage, your bird may be quiet, but not actually sleeping, so a sleep cage or sleep room is advised.
