I am trying to fill out the W3 Form and it asks for how many W2s are being submitted. Do you count each copy of the W2 (ex. copy A, copy C, copy 2, etc.) or do you just count the number of W2s with its 6 copies as a whole?

There is 6 copies of a W2. I have 12 employess that are getting a W2. So my question is basically, do I say that it is only 12 W2s being submitted, or do I count 72 W2s?
