To claim this credit in TurboTax Online:
Either select Deductions>Students>Student Profile from the side menu, or search for “Students” using the FIND tool, and then pick "Students" from the list. Check off "Tuition fees on a receipt, T2202, or TL11". Continue and fill in the tuition page. Then if you are eligible, you will see the Canada Training Credit page. There you will be asked for your Canada Training Limit from your previous year's NOA. Fill that in and it will give you a page telling you how much you can get, and if you want to claim the credit. Your student summary will show how much you are claiming on your return.
