Hi. I am filing amended return, as I forgot to add a W-2 to the original. Do I just send in a copy of the W2 that was not reported on the original, or all W2s?

If you are Amending your return to include an additional W2, you only need to include the W2 that was not reported on your original return with your Form 1040-X.
