You should report it under foreign income in the "Foreign" tab where USD will be converted into Canadian currency. Moreover, CRA allows you to claim foreign tax credit to reduce double taxation.
However, entering foreign amounts depends on the version of the software that you are using in TurboTax.
- The amounts that are reported on T-slips must be converted into Canadian dollars before entering, using an average annual exchange rate. In other words, foreign currency reported on T-slips has to be converted into CDN.
- You do not need to convert the amounts that are not reported on T-slip, TurboTax will convert the amount according to the exchange rate entered by you.
You can find the instructions on how to enter your slip amounts based on the version of TurboTax in the following link: How do I report foreign income, foreign pension, and other foreign amounts?
