Why is it asking for an earlier year lump sum social security worksheet when I don't have a lump sum this year?

[MichaelDC]

If there was no lump sum payment on the SSA-1099 for 2017 and you answered the question as No after answering as Yes and the program still wants you to enter the lump sum information, then you need to delete the Social Security benefits worksheet and re-enter the SS tax data.

Click on My Account at the top of the program screen.  Click on Tools.  Click on Delete a form
