Can i get 1040nr-ez form? because i filed resident instead of non-resident. as you know i didn't file 1040nr-ez form. but sprintax asks me informations from 1040nr-ez

There is no Form 1040-NR-EZ in TurboTax. If you are a nonresident alien you cannot use TurboTax.

If you need help with Sprintax you will have to contact Sprintax support. We cannot help you with it here. Here is a link to the Sprintax "Contact Us" page.

SprinTax and J1 Summer Tax Back are pretty similar, I have used them both and got good results even though J1 Summer Tax Back is a bit cheaper.
