Will I get the stimulus checks?

Hi, I turned 18 this year but have been filing my taxes since 2018. I’ve been claimed as a dependent in 2018 and 2019 but not for 2020. I was told I could still get the first two stimulus checks so I amended my 2020 tax return and am waiting to see if that goes through. My question was if it’s possible my amendment will get rejected and if I qualify for this third check. I checked on the IRS website and it says the payment status is unavailable for the third check. Any insight is helpful, thanks in advance
