It really isn't clear to me whether you are talking about
1) state taxes withheld on a "Distribution", as reported on a 1099-R?
Or
2) Do you actually mean "Contributions" to the retirement system, as listed on your W-2?
If #2, then it depends on which state you are asking about.......because some states report retirement system contributions as one of the box 12 entries, and others only as box 14 entries.
