Your unused RRSP contribution amount from previous years will be on your RRSP Deduction Limit Statement, found on your latest CRA Notice of Assessment. When you use CRA Auto-Fill my Return, TurboTax automatically downloads the contribution amount (if applicable) into your tax return for you.

Note: Unused contributions are different from unused contribution room, which is the amount you're entitled to contribute and deduct, minus the amount that you actually deduct.

Please follow the steps in link below to add unused RRSP.

How do I claim unused RRSP contributions I made in previous years but didn't deduct?

Thank you for choosing TurboTax.
