How to do a schedule 7 for the previous year?

[glen12]

I added money to an RRSP after Jan 1 and before Mar 2 2020
Do I need to refile the entire 2019 tax return?

Fortunately, you do not need to refile your entire 2019 tax return. You can simply make a change to your return as seen in our TurboTax FAQ link below.

I have filed my tax return. Can I still make changes?

Thank you for using TurboTax.
