Yes you owe it back. Sorry you already got the 2800 3rd Stimulus payment in 2021. Even though it was more than you qualified for based on your 2021 AGI income. But you must have answered a question wrong and said you didn't get it. Line 30 is only if you didn't get the full amount or qualify for more.
Oh wait, it's on line 31? Line 31 comes from Schedule 3. What line on Schedule 3?
