I have a 1042-S form stating my exemption tax treaty with zero for federal tax withheld and thus, I can't enter any value in other miscellaneous income.

You need to file Form 1040NR U.S. Nonresident Alien Income Tax Return.  TurboTax doesn't support this form, but we have a partnership with Sprintax offering a nonresident tax filing solution to our TurboTax customers.

Visit TurboTax Sprintax for more info or to get started.
