Stae Distributions on 1099-R

I have no box 16 on my 1099-R from OPM, but Turbotax demands an entry.

In addition, I moved mid-year, so I have two box 14s and two box 15s (one of each state).

I think Turbotax wants me to pretend I have 2 box 16s. although it's not clear where to enter, nor what the entries should be. Do I apportion box 1 or 2a for each state??? Where do I enter it?
