Are you using TurboTax Desktop or TurboTax Online? 

Yes using Turbo Tax online 

In TurboTax Online, you can just fill out the Principle Residence section, and it will ask you how long your home was your PR to determine how much you need to pay in Capital Gains. 

But, unfortunately, we are still still working on that form, so it's unavailable at the moment. It should be available after March 5.

Any update on when this form will be available???

Unfortunately, the forms are still locked. We're working hard to finalize these forms to align ourselves with CRA requirements ASAP. We appreciate your patience.

You can see a list of Forms that still locked here: Why does TurboTax say my forms are locked or haven't been finalized?
