international student

Hi,

I'm an international student on F1 visa. I already filled in the form 1040 on turbotax, and now I know that TurboTax isn't used for the non-resident.

How can I fix it? 

When I fill in form 1040 NR in sprintax, they asked me like filling the new form 1040NR or correcting the form filed to IRS? Which ones I should choose?
