What do you do if your mother files you on her taxes without your knowledge and you flie for yourself and they block it?

First, the Introductions forum (where this was moved from) is clearly marked as not a place to ask questions. That's why your question has been moved.

Secondly, we need more info. How old are you? What do you mean by
"blocked"?

If you are a dependent that is if your mother can claim you a dependent, then you can't claim your exemption.
It is not the other way around. So if your mother can claim you a dependent, you will have to amend your tax return.

Agreed.
