Can I just select code D? In my box 12 on my W-2, I have a code of D20 but there is not a code D20 to select.

No, the code in Box 12 is pretty important. Look over the W2. If it shows D20,ask your employer what it should be. 

Here is a link that tells what the different codes in Box 12 mean.

I have the same problem. I have a D20 and D. TurboTax will not let me put two lines with "D" because it is flagged as a duplicate. However, there is no way to type "20" next to the D. Per the IRS guidelines, it says to add the year "to the left of the line" 12a - 12d.

Add the two amounts together and enter that amount with a code D in box 12.

IRS W-2 Instructions page 19 - https://www.irs.gov/pub/irs-pdf/iw2w3.pdf#page=19

If any elective deferrals, salary reduction amounts, or nonelective contributions under a section 457(b) plan during the year are make-up amounts under the Uniformed Services Employment and Reemployment Rights Act of 1994 (USERRA) for a prior year, you must enter the prior year contributions separately. Beginning with the earliest year, enter the code, the year, and the amount. For example, elective deferrals of $2,250 for 2020 and $1,250 for 2021 under USERRA under a section 401(k) plan are reported in box 12 as follows.

D 20 2250.00, D 21 1250.00. A 2022 contribution of $7,000 does not require a year designation; enter it as D
7000.00. Report the code (and year for prior year USERRA contributions) to the left of the vertical line in
boxes 12a through 12d
