How to file unused rrsp contribution from previous year?

[TurboTaxSusan]

If you are using TurboTax Do It Yourself (Online), and you submitted your return using NETFILE, you can login to the previous year and use ReFILE to add the contributions to your return.

This TurboTax Canada FAQ tells you how you can adjust your return using ReFile: I've filed my tax return. Can I still make changes?

You can login to TurboTax Do It Yourself (Online) 2023 here: https://ww1.2023.ca.turbotaxonline.intuit.com/

You can login to TurboTax Do It Yourself (Online) 2024 here: https://ww1.2024.ca.turbotaxonline.intuit.com/

If you can’t use ReFile, then you can also make adjustments using the Canada Revenue Agency’s (CRA) My Account service or you can print & mail a T1-ADJ T1 Adjustment Request from their website.
