The code D represents elective deferrals under a 401k plan which can be made with pretax or after tax dollars of the employee's salary and is nontaxable. The 21 designation simply refers to the year the contribution was made and has no bearing on the taxable event for this .Thus, you may go ahead and omit it. I would doublecheck with your employer as to why the two D's are reported on two seperate lines and whether they should be combined.
Enjoy the rest of your day.
