I submitted my tax return, got a rejection email, was told I already filed. Apparently, my father had filed me as his dependent. How do I fix this? What are the steps?

If you want to e-File you must mark your return "someone can claim me" in Personal Info. (recommended)

If you don't want to make this change you will have to file on paper via US Mail.

I'm trying to claim myself, so I don't want to make the "someone can claim me change". What paperwork do I need to include in the mail?
