Did you receive a Form SSA-1099 with these payments included in the amount of benefits paid shown in box 5 of the form? If so, then you have to enter the SSA-1099 on your tax return. After you enter the amount from the SSA-1099 you will be asked if you received any lump sum payments. Answer Yes and then follow the interview to report the lump sum amounts by year.

After you enter your SSA-1099 information, we'll ask if you received a lump-sum Social Security payment.
Answer Yes and follow the instructions. Your SSA-1099 lump-sum section breaks down the payments into what amount was received for each preceding year. You can only enter one year at a time. If you need to enter benefits received for a different tax year, select Add another lump-sum payment.
While your lump sum may include benefit payments for more than one year, you do not have to file an amended tax return for any prior year. You might need to pay taxes on a small portion of your lump-sum payment.
After you enter your lump-sum Social Security payment information, TurboTax will automatically figure what if any taxes you owe due to the lump-sum payment.
