Could you clarify your situation?
Are you a nonresident alien? If so, TurboTax doesn't support IRS Form 1040-NR (U.S. Nonresident Alien Income Tax Return). See the TurboTax Help article Does TurboTax handle Form 1040-NR for nonresident aliens? for more information.
If not, what is your citizenship status? Where did you reside during the year? Do you have a Social Security number or ITIN (Individual Taxpayer Identification Number)?
Any other information you might provide could be helpful.
