State tax filing

I'm assuming the form you received looks something like this, with only one or two boxes filled out in the corrected column. Is that correct?

If so, they are only reporting the corrections and some employers do not fill out the form completely. You would use the information from the original W2. The only changes or additions you would make are what is listed in the  corrected column. 

For instance, if box 2 is filled in on the W2C, but nothing else, you enter the information from the original W2, with the exception of box 2. Your entry for box 2 would be the amount shown on the corrected form.

Does that make sense?

Let us know if you have more questions.

So sorry for your loss.
