I entered my husband T4A statement of pension, retirement, annuity but it’s a cancelled form because we placed his pension in a RRSP. How can I mentioned it on my file?

You will enter your T4A as you did, then you will need to mark the RRSP contribution as a transfer in the RRSP section of your return.

When in Easy Steps you will click on RRSPs then scroll down till you see Transfers to RRSPs- click there and you will see where to enter the amount transferred.
