I have a client who received one of those for years.  It also showed uncollected SS tax on the "wages," which had to be shown on a different form and carried over to a separate schedule, or maybe it went on a different schedule that carried over to separate form.  This year, there was no W-2, and I asked why.  Turns out the insurance amount had been reduced below $50K, probably because she turned 65.  

For an $11 credit, I would ignore and override.
