Wondering about the answer to these hypothetical client questions:

In 2019 I was a dependent and in college full time. My parents claimed me and they got $500 for me as part of the stimulus. But in 2020 I was independent and I plan to file my own taxes. Will I be able to claim my $1200 as part of the first stimulus on my 2020 taxes?  And oh, I forgot. Will my parents have to pay back the $500 they got for me for the first stimulus if I get $1200 for it on my 2020 taxes?
