My wife changed employers mid year and has a total of 3 W2's from 2 employers. The sum total of Box 4 on the 3 W2's is 10557.55. I have a single W2 and the amount in Box 4 is 8853.60 .
We simply uploaded our W2's in TurboTax and seems like it made the calculations correctly.
Also, none of the W2's say Code A in box 12
