Getting started

I appreciate the added information but it is not fully answering my question, although I think we are close.

When I am done filling in the information and doing the final review of my tax return, I am looking at a year-over-year comparison which clearly shows a value under the "Net Income" section for "RPP" which has a value of box 20 from my T4 instead of box 52 (total RRP contribution for the year). I believe this is wrong.

The total value of my RPP contribution (box 52) should be used to reduce my total net income as it is a tax shelter for the year. Can you explain why the TurboTax software uses the value in box 20 as the amount to shelter and not the total amount from box 52 please.
