"about other things in Box 14 such as union dues not being handled correctly"

Box 14 is informational purposes only. Whether or not there is anything to handle depends on the taxpayer's other situations and conditions. The program handles it fine, because you figure out what goes where, if anywhere, for that info. There is no specific detail that flows from that box.

On the NJ 1040 you will see it, but you need to do more to get it to work in Pro Series.
