Missed rsp from previous years

I realized I didn’t put in an rsp amount from 2023 Jan-March, it says to go to refile - next to that years tax form, but i can’t find that option on the app anywhere. Other then where it says ‘Make adjustments to your filed returns and submit them online to the CRA via ‘ReFILE’ in a blue box. This just brings me to a help page. Further the down the page there is a list of my old tax returns but the link only brings me to a pdf and no refile options 

After you file

You need to login to the 2023 version of TurboTax Online to ReFILE your return. You can login to TurboTax Canada Online 2023 here: https://ww1.2023.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. 

 

Please note: The CRA's ReFILE service is closed for maintenance and will reopen Monday, February 23, 2026 at 6:00 a.m. (Eastern Time).
