Maybe cleaning her room is overwhelming. You could break it down further to first, put clothes in the hamper, second, put toys in the box (if she uses a toy box), third, put books on bookshelf. You could stretch is out a few days. She can do one thing to clean her room each day. The time would be less and she would know the expectation. If she's visual, you could write the task and after she completes it, cross it off or check mark or sticker next to it.

My son was not wanting to do his school work at school. His special ed teacher made a check list of the tasks he needed to do. He got to put a sticker next to the task when he did it. Structure is so crucial to kids on the spectrum. Hard for me because I don't always want or like structure. Hang in there! A lot of trial and error for sure.

Get to her do the chores first when she wants something. My daughter is pretty lazy but she can do some things for herself. My daughter's time is wasted watching Youtube videos or looking at the phone.

That’s the thing. She won’t do it. She just has a meltdown instead. She won’t do it. I try to get her to do it. I try to help her and do it with her. I just end up doing it while she plays. Then she wants to go watch her show.
