On the back of the W-2 are instructions for box 12

Is there a 1 or 2 letter code in box 12?  You only need to enter box 12 if you have a code and amount.  The code is 1 or 2 CAPITAL letters like D or DD.

W2 Box 12a - 12d are just the box numbers.  They don't have to be filled in.  But if they have a Code (1 or 2 capital letters) and amount you need to enter it.  Don't confuse the lowercase letters a-d with the uppercase Codes A, B, C, D, DD, etc.  The lowercase a-d are just part of the box label. You don't enter them.  You can enter the Code and Amount in any box 12.
