My question is, when turbo tax starts on the Social Security questions, it automatically asks you for the amount in box 5 (lump sum). My box 5 has the entire lump sum listed (with the two previous two years). So do I subtract the previous two years and then put the remaining in box 5 or do I continue and add the entire amount of box 5 then fill out the prior two years and the software will deduct my prior two years from the initial lump sum amount I put in initially?
