Please clarify your situation.
Are you working on your 2017 tax return or your 2019 tax return?
If you are working on your 2019 tax return, do you have a Form SSA-1099 for 2019?
On your SSA-1099 for 2019, at the bottom on the left side does it show a payment in 2019 FOR 2017?
On your 2019 tax return you only report payments that you received IN 2019. TurboTax asked whether you received a lump-sum Social Security payment IN 2019 FOR a prior year. You do not report a payment that you received IN 2017 on your 2019 tax return.
If you did not receive any Social Security benefits in 2019, and you do not have an SSA-1099 for 2019, you do not enter ANY Social Security income in your 2019 tax return. If you did receive Social Security benefits in 2019, but on your SSA-1099 for 2019 there is no payment for a prior year at the bottom left, you do not report a lump-sum payment on your 2019 tax return. In this case, all the benefits that you received in 2019 were FOR 2019.
