When you are going through your return in TurboTax and enter your Social Security benefits, one of the questions on the following page is whether you received a lump-sum payment for a prior year as part of your current year payment. You would answer 'yes' and go through the questions for each year shown on your Social Security statement.
Doing this process for each prior year shown on your statement will determine what amount, if any, would have been taxable had it been included on those prior year returns. Since you typically did not file a return for those years, the Social Security would not have been taxable and there should be no impact on your 2022 return as a result.
As for the lump sum paid that would be attributed to 2022, unless you had enough other taxable income on your return, the lump sum may not be taxable either. It all depends on your filing status and your other income being reported.
