Code 56 is listed in Appendix B. under 1099-MISC income as a residual.
I interpret that to mean that you are not receiving this money as regular income you were trying to earn so it is not subject to self-employment tax.
Enter your form like this:
If the 1099-MISC is not a business, you have to mark:
Thank you! Would this make me eligible for the foreign tax credit?
You would only be eligible for a foreign tax credit if you paid foreign taxes on your foreign income.
If so, you can apply for the credit in the Deductions and Credits section of TurboTax, under Estimates and Other Taxes Paid, then Foreign Taxes. The credit would only be allowed to the extent of your US tax on the foreign income.
