Did you get another W2 for the same job? If you have another one for the same employer sometimes they will give you more than 1 W2 with just the extra info on it. If this is the case, list it all on the first W-2. Maybe they needed more lines for box 12. The W2 only has 4 lines for box 12 but you can enter more than 4 on Turbo Tax.
