Missed rsp from previous years

[Heatherlou867]

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
