How do I fill out the box 12 information from my W-2?

SOLVEDby TurboTax4088Updated January 13, 2023

The W-2 you got from your employer will have four lines for box 12—labeled 12a, 12b, 12c, and 12d.

Any amount on a box 12 line will also have an uppercase (capital) letter code associated with it. (If there aren’t any capital letter codes in box 12, skip it and move on to box 13.)

In each box 12 line, select the capital letter code from the dropdown and enter the corresponding amount. See the example further down to see what it would look like in the TurboTax CD/Download software.

Important: Don't confuse the lowercase box 12 letter (for example, the a in box 12a) with the capital letters in the dropdown. So, if your box 12a has the letter code D in it, select D (not A) from the dropdown. And if 12a is blank, leave it blank—don't select A.

To enter multiple box 12 amounts, select +Add another box 12 item.

In this fictitious (and somewhat unrealistic) example, the W-2 shows these box 12 amounts:

  • $5,000 in box 12a with code D
  • $5,000 in box 12b with code DD
  • $5,000 in box 12c with code W
  • Box 12d is blank

Here's what the entries would look like in TurboTax Online:

And here's what the entries would look like in the TurboTax CD/Download software:
