Retirement tax questions

If in each of those years individually  ... 1/2 of the SS benefits for that year + your other income for that year will exceed $32000 in total then all you need to do is enter the SSA-1099 form in the program and you can skip the lump sum questions completely as it will be a waste of time.    Otherwise follow the lump sum line of question ... you will enter in all the years separately.
