There are only four box 12 entries. If your husbands’ W2 has five entries in Box 12 then there would be a second W2 printed.
Thank you so much. I checked and that is the reason.
I always do our taxes because we do the one without deductions and this threw me for a loop. It’s always been straight forward before; one W2 for each of us, plug in the numbers, add, subtract and then write the check.
