How do I enter into the system that I am a non-resident F1-OPT?

[JohnR1]

As a nonresident alien F-1 visa OPT you will need to file a Form 1040NR, U.S. Nonresident Alien Income Tax Return, to report any U.S.-source income you may have. TurboTax does not support Form 1040NR, so you will not be able to use TurboTax for your specific tax situation.

You may want to check out Sprintax , who are specifically geared towards international student nonresident aliens with 1040NR filing requirements.
