In TurboTax Online, search for “RRSP” on the Tax Home page. On the "Your registered savings plan profile for 2024", make sure that "Have unused RRSP/PRPP contributions from prior years " is checked off. Then you can continue forward until you get to the "Unused RRSP/PRPP Contributions" page where you can change the amount.

Thank you for your help. I didn't give all my details earlier but found out after that I need to refile my 2023 tax return before I proceed with my 2024. I changed my 2023 total rrsp contributions online on cra site because of incorrect amount but didn't correct the specific amount on the schedule 7. This left me with unused RRSP contributions previously reported and available to deduct for 2024. Once the unused amount is removed by refiling 2023 change, I will be good to go. Appreciate the help but realized it is better to correct the situation rather than working around it.
