In the Search box type "foreign tax credit" (without the quotes), then click the link that says "Jump to foreign tax credit" and go through the screens. When it asks for the type of income select "Passive income." You will be able to enter the amount of income and the amount of foreign tax that you paid.
If you need further help with how to enter something, tell us whether you are using TurboTax Online or the CD/Download TurboTax software.
