The 2024 software does not have the correct boxes for CPP. Box 20 is "self employed income" and my T4A P box 20 is Taxable CPP benefits and the same for OAS. Update?

Please make sure that you are on the page for the right slip. 

T4A is the Statement of Pension, Retirement, Annuity, and Other Income.

T4A(P) is the Statement of Canada Pension Plan (CPP) Benefits.
T4A(OAS) is the Statement of Old Age Security.
