Retirement tax questions

I did  that - it's clearly wrong. The problem is what they include in line 1a, that is all. The whole calculation falls apart or not based on 1a. They are taking any kind of pension reported as valid for this calculation, that is incorrect. I didn't learn of the error until now, and the return questioned is 2017. So given it's a state return, some unusual requirements (over 65, non employee pension, 4 years ago before cited by the state), I figure it's just an obscure bug.
