As of April 5, 2025 the issue still appears for me. I called support and they agreed after screen sharing that everything is entered correctly. I deleted the T4 and tried again, same issue. Originally the T4 was imported from CRA. The second time after deleting I entered it myself. Same issue - the total CPP amount is included as an overpayment. I have both CPP and CPP2 - not sure if that is triggering the issue. Although I did try with and without different values - again - same issue. I have no pensionable earnings, this is a vanilla T4.
