@ahutchison2 - here is the issue.
Your parents have the option to claim you as a dependent or not claim you; the IRS doesn't care.
But from your perspective, what your parents decide to do doesn't change the answer to the question CAN some else claim you.
it is a confusing subject, and best if you just take 5 minutes and complete this IRS tool. Answer the questions as if you were your parents; it will tell you if they CAN claim you or not

If you can't be claimed by someone else, then yes, you can claim the Recovery Credit and it will be on Line 30 of your 2020 tax return. The fact that you were a dependent in 2019 is immaterial.
