It sounds like Code D and the amount is $21. Code D shows the part of your pay that went toward a 401K. This is informational only. It shows the amount of income that is deferred and is not included in Box 1 of your W2. Therefore it will not be taxable now but when you withdraw from the 401K in the future.

....If there is an actual $ amount alongside?

THEN the D21, is just a "D".....

..the 21 just indicates that some of the $$ contributed was to pay for some 2021 TSP/401k contributions that were not done during 2021. The "21" isn't entered.
