It depends.
If the amount of stimulus she is entitled to based on her 2020 income is greater than what she actually received, she will receive the difference as the Recovery rebate credit.
However, if what she actually received is more than what she is entitled to, she does not have to repay the difference.
Please read this IRS document on how the stimulus is adjusted for people with income over the threshold.
