To clarify, my original W2 has WI in box 15 and does have a value in box 17, however in my filing I had put down PA instead of WI. That was my own error. But my employer also should not have had WI as my state as I've always worked from PA. (Also not trying to justify my mistake, I definitely didn't intend on having the incorrect state based on my W2)
I have received two W2-C's. The Previously Reported box 15 shows PA with box 17 at 0.00. The Correct Information side has PA on box 15 and does have an amount for box 17
On a second W2-C, the Previously Reported box 15 shows WI with an amount in box 17. The Correct Information side box 15 shows WI and has no amount for box 17.
So the main concern I have is that the two mistakes (Mine and my employer's separately) means what I previously report isn't far off from my actual obligation but I don't think PA actually received withheld money from my employer.
