W2 with zero income

Hello. We have a W2 where my wife worked previously. She left 2016. She received a W2 with zero amount in Box 1, and all the other boxes except 14 and 16, where there is the same amount ($14 and change). Apparently when she used one of their apps last year to purchase, her discount privilege while still working there, should have been turned off 3 years ago, kicked in. Should we still include this W2? It is not letting us eFile. Thanks everyone!
