@bobo_fly2012 - The W-2 box 12 code "DD" is for your information only. It does not affect your tax return in any way. In fact, it is OK to ignore it and not even enter it.
If for some reason, it did change your tax then it was entered incorrectly ( a code "D" can affect the tax return if one "D" of the code "DD" is missing). I suggest you totally delete the W-2 and re-enter.
