I think there may be a difference with TurboTax this year.
I have never previously entered Box 26 before, usually leaving it 0.00. I think TurboTax now needs that amount to calculate the CPP remittance properly. In previous years I believe this wasn't the case.
In many cases Box 26 and Box 14 are the same. I entered the same amount in each and the overpayment issue is resolved.
It would be good to get more confirmation from TurboTax about this situation.
