No you get to keep the $1400 --- you do not have to pay it back. Since you are 24, the only way they can claim you is if you had less than $4300 of income in 2021. Does that fit? If they claim you they get a $500 credit for other dependents. If their income is too high they do not get the $1400 for claiming you.
