Ok I did it but didn't file yet. It totally changed her refund. She was getting $582 federal return and $12 ca state refund.Now she will owe $176 federal and $3...

Ok I see how to amend her tax return. But will it affect her refund that's she's getting?

Unfortunately she chose that she's not being claimed as a dependent and her tax return is already filed.What can I do to fix this?
