Stimulus check from tax retuen

Hi There, in the year 2020 my mother claimed me so I did not receive any stimulus and she didn't receive any money from me either due to my age. I was told that stimulus that wasn't paid in 2020 could be paid to you through your tax return. I wondered if I was able to claim my stimulus because I didn't receive any in 2020 due to my mother claiming me or would I get in trouble with the IRS

Thanks!
