All versions of TurboTax have all the forms and schedules you need to prepare and file a complete and accurate return. However, TurboTax Premier is the product we recommend if you have things like investments and capital gains/losses.

I did as suggested and upgraded to Premier.  However, once in the Premier version, I searched the form T1170 and nothing came up - let alone the schedule 3.  I have also heard that one has to paper file in this instance.  There doesn't seem to be a firm answer for my case and I'd really appreciate the right guidance.
