Yes, that amount down in the corner is your lump sum. When you got that payment for the Fairness Act, most of the payment was the retroactive amount for 2024, and then for 2025 you continued to get a higher amount of SS benefits.
If you used desktop download software to prepare your 2024 return, the 2024 return is stored only on your own hard drive. Find it and look at your 2024 AGI to help you decide if you want to assign that lump sum to 2024 or to 2025. If you want to assign it to 2024, you just make that choice in the 2025 software. You do not have to amend 2024.
