Hi
Unfortunately you can't, and if you override the amount, CRA will adjust your return. You have to claim your carry forward amount in the first year that you have to pay income tax.
Please, check this CRA link for confirmation: https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-re...
A professional advice would be to contribute the refund you will get this year in an RRSP plan but not deduct them on the same year. You can carry forward the RRSP contributions and claim them whenever you wish.
Thank you for choosing TurboTax
