Missing description for Box 14 on W-2

Box 14 on my W-2 has an amount in it but there is no description (significant amount in the hundreds).  I left the description blank, entered the amount and selected Other (nonclassified).  Turbo tax however keeps flagging the w-2 as needing review and forcing me to come back to it.

 

I have deduced from paystubs that this is my retirement contributions to a 414(h) plan.  Box 13 (retirement plan) is not checked.  On my paystub it is listed as PENSION.  Not sure what to do from here.

 

Thank you for any help!
