You ask for a passed (2007) ssa disability payment. When I recieved the lumps sum I reported it on my 2007 1040 and paid any fed tax due. I am not sure I still have the 10 year old tax form. Can I just say I did not receive one and move on or what.
Yes. If you did not receive a lump-sum of social security in the tax year 2017, then you should say no.
If you have no repayment of any social security that was received in a prior year there is nothing to report in the current year for repayment.
Report only the social security received and reported in box 5, of the Form SSA-1099. (Click the image attached to enlarge and view for assistance.
