Need Help for box 20 on t4 slip.

Company for many years entered amount in box 20 of my T4 SLIP. This year they sent an amended T4 saying box 20 will now be blank, as Industrial Alliance NOW sends receipts. So now where do I enter the amounts on T1 GENERAL?

Getting started

Box 20 of the T4 is for contributions to an RPP. In TurboTax, you enter your RPP contribution amounts in the RRSP section.
