Enter your foreign interest as if you had a 1099INT for it. If you paid foreign taxes, enter them in box 6 of that 1099 INT. This should also generate schedule B. You'll need to fill in part 3 of that.
You can also enter "schedule B" in the search box and then choose from the drop down which part you want to work on.
Turbotax does not support the FBAR from Fincen 114, which you need to file if you have $10000 or more in your foreign accounts. You have to file it through the Treasury website: http://bsaefiling.fincen.treas.gov/NoRegFBARFiler.html
