@VolvoGirl ..Yes, they are both 401K deductions and both are coded with just the letter D. One amount is listed on line 12a and the other amount is listed on line 12b. There are no other numbers shown in the boxes to indicate that either of those amounts were for a previous year's withholding. I added them together and put the total into line 12a, since the total of the two amounts equals to what was withheld out of the wages listed in box 1 on that w2 form.
