You told me that I have to file a 1042-S separtely, but where do I list the income in the turbo tax return?

You do not report your Form 1042-S in TurboTax.  Form 1042-S is not supported by TurboTax.   Form 1042-S does not have to be filed with your tax return you will mail your Form 1042-S to the address specified in the form instructions.
