If you are a nonresident of the US (see substantial presence test calculation below), you need to file a nonresident 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.
