My mom has a co pay. We have never charged her. Not sure how to file tax return.

I, too, am confused.

What copay? What is the "whole copay" that mom, evidently, should be paying.

Are you being paid to care for her? Are you and/or son providing medically necessary care?

Sounds like a consult with an elder law attorney is a good idea to determine if mom is now your dependent.

Could you provide a few more details? I’m a little confused by what you wrote. What is the co-pay for? I’m only aware of an insurance co-pay for medications or health care. I’m also not certain what you mean by primary care aide. Do you mean POA? And what is a “p/t” agency. Are you an employee of this agency?

In any case, it would probably be in your best interests to see an accountant or a professional tax preparer who can give you advice based on your specific situation.
