I am an international student, and I have filed the tax through turbotax. Since, I was not aware of any additional forms. What should I do?

If you are F-1 visa and have not yet passed the five year exemption period, then you are  most likely still a Non-Resident Alien and therefore need to file form 1040-NR ( not supported by TurboTax ). If you have already filed a form 1040 using TurboTax, you need to file an amended return ---- please visit  SprintTax ( TurboTax  partner ) or a Tax professional or your school foreign student office for help
