My W2 has two entries for Category D which one is for 2024. When I enter both in Turbo Tax, it tells me it's a duplicate entry but there are actually 2 of them on my W2?

One is D 24 and the other is simply D. I also have a DD but it won't allow 2 codes for D.

When entering multiple Box 12 entries with code D in TurboTax, if one is specified as for 2024 and the other just D, TurboTax may consider them duplicates because it only recognizes the base code D. TurboTax allows up to four Box 12 entries (12a to 12d), each with a different code. To avoid the duplicate error, enter each amount on separate Box 12 lines using the + Add another box 12 item button. 

If TurboTax still treats them as duplicates because of the code being the same, you may combine the amounts or clarify with your employer which entry to report.

Regarding Code DD, it represents employer-sponsored health coverage total cost. This code is informational and does not affect your taxable income. You should enter Code DD and its amount exactly as shown on your W-2.

To enter multiple Box 12 entries with code D and DD in TurboTax online, follow these steps:

1. Go to the Wages & Income section and select Add a W-2.
2. Enter employer details and proceed to the Box 12 section.
3. For the first code D, select D from the dropdown and enter the amount exactly as shown.
4. Click + Add another box 12 item to enter the second Code D if TurboTax allows it; if not, combine amounts or check with your employer.
5. Enter Code DD and its amount separately on another line.

Remember: Box 12 entries must exactly match the codes on your W-2, and TurboTax limits one entry per code, so identical codes for different years or variations may not be accepted separately.

If you have two Code D (like one with the year ie: D24) Either combine them or leave off the D24.  24 refers to the year 2024.
