You will report your foreign bank interest the same as you would CAD interest. It will show up on Line 12100 of your tax return and can be entered in TurboTax by going to Income > Investments > Interest on Bank Accounts not Reported on a T-Slip. Or you can use the "Find" button and type in "Interest" to find that same spot.
Just remember to report any foreign interest in CAD dollars. The following link will give you exchange rates to use: Bank of Canada - Annual Exchange Rates
