Get your taxes done using TurboTax

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.
