Follow the steps below to arrive at the results you need. The lump-sum election has always worked correctly in TurboTax. Have your 2021 tax return available which is included in the lump sum payment (shown on your SSA-1099).
This can be handled on your tax return for 2022. The Form SSA-1099 should show a total amount in box 5, and then the amount that is designated for each year in box 3. Worksheet 4 is included after Worksheet 2 is completed for each year.
Be sure to select "lump-sum" method of reporting in this situation which is all done on the tax return for the year of receipt of the benefits. Enter the appropriate amounts for each year when you start that section of your return. Continue to add each year for all years listed in box 3. There is no amendment required.
Also enter a zero if your Social Security benefits weren't taxable or there were none in the earlier year (such as for a spouse). If you are using the TurboTax CD/Download version review the Lump-Sum Social Security Worksheet in Forms. You can also review 'Earlier Year Lump-Sum Worksheet' for each year.
