So looking at it more carefully, I guess it's one single W2...but with three versions. (1) W2 - Federal Filing Copy, (2) W2 - DC State Reference Copy, and (3) W2 - MD State Filing Copy. Sorry for the confusion.
So I'm pretty sure IRS is just getting a single "wage" from Box 1...and not the accumulation of all Box 1s.
Also the company uses ADP for their payroll...so I'm assuming that the W2 is legit, just a different way of differentiating federal and state taxes and not the itemized multi-line in Boxes 15-17 you are describing.
Regardless, DC (Box 16) + MD (Box 16) should equal Box 1...which it is not. I have just sent my company a request to look in to the discrepancy.
Thanks!
