I need to change the EIN for one of my W2s, but my taxes are already set to be printed and I can't change them. Do I need a 1040X or can I change my printed return?

The accountant for my employer printed the wrong EIN on the W2s, and sent the correct ones after I had submitted to be filed. All of the information and values are the same. The only thing that changed is the EIN. Can I just white out the EIN on my printed return and replace it with the correct one?  The correct W2 does not have anything that says CORRECTED on it.
