Questions about 1040NR EZ and 1040X
Hello,
I am doing a 1040X and a 1040NR EZ in order to amend a return that I submitted by mistake as a 1040EZ through TurboTax when I was on my OPT. One of the questions asks if the person has filed a U.S. income tax return for any prior year and to write the year and number form. The problem is that I also did taxes on 2010 but I did it with the help of some volunteers from my university. I don't remember which form number they used and they did not keep any records.
So what should I answer in that question?
I am also worried that I can get in big trouble like jail or something for having filed the 1040EZ with TurboTax because I did not know that I should had filed a 1040NR EZ at the time. I no longer live in the US but I would like to correct this mistake.
Thanks
