NJ State Employee - How to report w2 section 14 401(a)?

My wife works for NJ in education and on her W2 section 14 there are 3 codes.  One of them is '401(a)'.  

 

It looks like this is capturing her retirement contributions?  

 

In turbotax I don't see a '401(a)' value when I input her W2 details.  Which value do I select?
