First, confirm the Federal Employer Identification Number (FEIN) is the same on both W-2's. I am assuming it is.
You will enter the W-2's "as if" all of this was reported on one W-2. Employers will do this when there is not enough room on a single W-2 to enter information for multiple state taxes in boxes 15-17. So enter it in the program as a single W-2. When you get to boxes 15-17, after you enter the data for the first state reported on the first W-2, a new row will appear so you can enter the data from boxes 15-17 for the 2nd state, from the other W-2.
