Retirement tax questions

I am getting the same thing.  I did my taxes about 2 weeks ago and never got that message but hadn't filed yet.  Just went through again today and came up all of a sudden.  All SS takes box 4 are 6.2% of box 3.  Called TurboTax and spoke with them and they didn't know and thought maybe I'd be getting a  W-2(c).  Tried to explain that this issue came up today etc.  

 

We are still able to file and (like above) seems to be a glitch as it wasn't there over the last couple weeks (all my W2s were in and this never came up).

 

Figure I'll file next week regardless but all SS takes are paid correctly.   Thoughts?
