After you file

Hello, Thank you for your quick response.
I got a  more question,

I still get my Tax Return money after amending, So my parent's have to amend a paper form to IRS so they can get the tax break correct? I'm 20 year old, still trying to figure out about Tax Return policies and whatnot. I accidentally did the tax return as a independent since I'm a veteran for US Navy, and they told me I'm independent.

Do I get any penalty for amending from independent to dependent on my parent's tax return?
