If the Employer ID number is the same for both states W-2's, you will want to just enter one W-2 form. If the amounts in boxes 1 - 14 are different on each state copy, then you would want to combine them. But if the amounts in boxes 1 - 14 are the same, simply enter the amounts from one of the forms.
Then, for boxes 15 and higher, enter the amounts for each state on the W-2. Enter the first state information and then select to Add Another Row. See the sample screenshot attached.
