You’ll see the following error message in H&R Block’s 2017 tax software if you entered your taxable CPP/QPP benefit amount in box 20 of the T4A(P): Statement of Canada Pension Plan Benefits page but didn’t indicate the number of months you received CPP/QPP retirement benefits during the year in box 23:

You reported taxable CPP/QPP benefits in box 20 on the T4A(P) slip, so you need to report the number of months of retirement in box 23, as shown on the T4A(P) slip. [error code: 123]

How do I fix this?

To correct the error, return to the T4A(P) page in the tax software and enter the correct values in box 20 and box 23, as shown on your T4A(P) slip. If you didn’t collect CPP/QPP retirement benefits during the year, enter 0 in box 23.

Note: You can enter your T4A(P) slip on the QUICK SLIP page under the QUICK ENTRY tab. Simply type "T4A(P)" in the search field and either click the highlighted selection or press Enter to continue.
