Just contacted my employer again (and its a government branch of Ontario) and they said the reason why the second T4 statement has an amount for box 16A, and not 16 is due to the fact that both T4s are from the same employer and that the second T4 cant have an additional amount in box 16 as I maxed that out with my income/CPP payment on the first T4. They claim its accurate, and that they have had no issues of problems other than this glitch from turbo tax users. So, for example, if on the first T4 a person maxes out their CPP contribution ($4034.10 for the 2025 year), then the CPP2 kicks in...which has a maximum amount also ($188.00). So on the first T4, you could have a maxed out CPP ($4034.10) for box 16, and PART of the CPP2 for box 16A. Then if the SAME employer hires you for additional work (like a summer gig), they cant deduct more CPP (box 16) as you already reached the maximum in the first T4, but CAN deduct more from you in CPP2 (box16A) until you reach that maximum amount ($188.00).
So please update the software to allow people to proceed. You could tell the software developers that if a previously entered T4 hits the maximum CPP amount, its possible for a second T4 to include an amount for box 16A without an additional box 16 amount, so long as the previous T4 box 16 is maxed out at $4034.10).
Please, please, please fix this!
