Without knowing more information, it is difficult to advise you. My first recommendation is to obtain an ITIN from the IRS or plan on applying for one when you file your taxes for 2015. Please follow this link for more information https://www.irs.gov/Individuals/General-ITIN-Information
Please review IRS Pub 519 for more information on your situation. https://www.irs.gov/publications/p519/ch01.html
If you are a nonresident alien, the correct tax form for you is a 1040NR. TurboTax does not support that form.
