Multiple W-2s for Same Employer in Different States

I have 4 W-2s from 4 different states. I entered each W-2 individually per state. The info is the same from box 1-10 through the employee info. From box 11-20, each of the 4 states have different information. The non-resident W-2s are blank through box 10. TT won't allow duplicates. So I delete the individual entries and add states to the original W-2.  TT won't allow multiple Box 12 entries. It sees them as duplicates.

Three of the W-2s have different employer ID numbers for the state ID. New York has the exact same federal & state employer ID number.

Help?

Thanks!
