How do I actually calculate the return of excess if I have two employers? for example: First employer's W2 states $10000(DD) in box 12a, $19000(E) in box 12b, and $2000(CASD) in box 14. Second employer's W2 states $18000(D) in box 12a-d, and $1000(CASDI) in box 14. What is the actual formula to use?
