Turbo tax has asked about my employers PRPP contribution. In addition to RRSP, we have DCPP. DCPP is not mentioned. Does this need to be highlighted?

If you make employee contributions to any registered pension plan (RPP) and these are recorded in box 20 of your T4, then the amount is not only a deduction from Total Income but also is part of your pension adjustment (PA). This means that it will reduce the amount of RRSP deductibility you earn, as reflected by Amount A on your Notice of Assessment.

Here is more great information concerning DCPP.
