If you have been in the US less than 5 years or part years, you need to file a nonresident US tax return.
TurboTax does not support nonresident returns.
However we have a partnership with Sprintax offering a
nonresident tax filing solution to our TurboTax customers.
Visit
the TurboTax/Sprintax site for more info or to get started.
Sprintax should be able to assist you with your tax question.
