You will see the following error message in H&R Block’s 2016 tax software if you entered a taxable CPP/QPP benefit amount in box 20 on the T4A(P): Statement of Canada Pension Plan Benefits page but did not enter the corresponding disability benefit amount into box 16:

You reported taxable CPP/QPP benefits in box 20 on the T4A(P) page, so you need to report the amount of disability benefit in box 16, as shown on the T4A(P) slip. [error code: 121]

How do I fix this?

To correct the error, refer to your T4A(P) slip and enter the correct values shown in box 20 and box 16 into the designated fields of the tax software. If you didn't collect a disability benefit amount, enter 0 in box 16.

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