You keep repeating your first question. How much over 75,000 did you make? It phases out between 75,000 and 99,000. So you will get less than the 1,200 and 600 for the 2 rounds.
If you were claimed as a dependent in 2019 but not in 2020, you can still get the Recovery rebate credit on your 2020 return even if your parents got it for you. And actually if you were over 17 in 2019 they did not get it by claiming you as a dependent. They only get it for dependents under 17. They don’t have to pay any back.
