If your employer issued two W-2s, the important thing is the wages in box 1. If they are the same, it will be obvious that there is a mistake on the employer side. You can enter only the correct W-2, in this case. The IRS will look at the newer one. The employer should correct it but keep in mind, corrected W-2s are a high audit item. If they didn't correct it specifically, just go by the W-2 that you know is correct. If the wages are not the same in box 1, then you DO need to ask the employer for a formally corrected W-2.
