Stimulus money and family

Hi, my parents filed me as dependent in 2019 and I filed as independent in 2020 due to my entrance into pharmacy school. However, they received a 1400 check for me because of 2019 and I may qualify for the 1400 stimulus because of my 2020 taxes. Should my parents return the 1400 received? Or should I return the 1400 when/if I receive it?
