You received CPP or QPP retirement or disability benefits but did not enter the number of months from box 21 or box 23 of your T4A(P) slip. I keep getting this message

If boxes 21 & 23 are correct, please check the other boxes. For example, if you were only retired, you should have an amount in box 14, not box 16.

If you are still not able to resolve this issue, please contact our phone support team at 1-888-829-8608.
