I have only self-employed income so a CPT30 should not be used, only the month indicated on Schedule 8, to stop CPP contributions because I turned 65 in 2021. However, TurboTax flags that as an error unless I indicate that I have filed a CPT30. I have not opted to start CPP income yet and TurboTax shows that as an error as well saying I cannot stop CPP contributions unless I have started CPP income which is not true. Any suggestions or help?
