You will have 3 lines entered for Box 12. To enter multiple box 12 amounts, select +Add another box 12 item.
How do I fill out the box 12 information from my W-2? Click that link to see an example.
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.
In each box 12 line, select the capital letter code from the dropdown and enter the corresponding amount.
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.
