@raj98 , since you are still a student ( in training -- OPT/STEM ) you are still immune from FICA regs -- see this :
Student FICA exception | Internal Revenue Service
On your W-2 Box 3,4,5 and 6 should be empty. So when you enter you Social Security Wages as blank, TurboTax may ask you to verify this but will also compute NO Social Security taxes. Ditto for Medicare wages and tax. Thus there should be no issue your recognizing the FICA exception.
Does this help ? Is there more I can do or you ?
