on box es15 of the w-2c there's either one or both states listed (Wi and/or Pa) and in box 17 there is the w/h for that state.
what was in box 15 of original w-2? was there w/h in box 17 don't need the amount
what is in box (es) 15 of w-2c and is there an amount in box(es) 17 if both states is Wi showing zero. for box 17
from your original post it appears you filed a WI return and reported the w/h as shown on the original w-2, you did not mention whether you filed a PA return which as your resident state was required.
if this is correct the w-2c should show 0 WI wages but the amount WI w/h. if I'm correct you need to file an amended nonresident WI return to get back the w/h
the w-2c should show PA wages don't know if it is showing PA w/h that is different from the original w-2. if so you need to file an amended PA resident return,
