Retirement tax questions

I myself have already told them this cannot be correct as I've had the same insurance through colonial for years and it has never been coded as such(my employer changed to quick books this year who now does their w2s). I am going to talk to them again and show them what you've said. Just to be clear, my colonial insurance is in no way a HSA. Also, what should it be coded as if anything? The only other code I recall being there is DD, but that was when my employer paid half of my health insurance.
