Why enter lump sum ssa from 2007 on 2017 1040. I reported and paid the taxes for ssa lump sum 2007 on 2007 tax form

The question only refers to receiving a lump sum SS payment in 2017.  If you did not receive the lump sum payment in 2017 then answer question as No.

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.
