Yeah, it's a glitch introduced by last night's software update.
One person found that increasing his box 4 value from $$$.36 to $$$.56, was successful in getting rid of the notice. I tried his W-2 numbers and $$$.50 lost the notice, but $$$.49 did not...which is exactly the point where rounding intrudes.
But leave your number as they are and ignore it if you are sure that box 4 (in the software form) is 6.2% of box 3 .........(unless you want to test it yourself...but make sure you return the value of box 4 to what is on your W-2).
