@isabellaam simply, if the income was from W-2s, was less than $12,950 in 2022, there is no reporting requirement, If there was any federal tax withheld (and you are stating there wasn't), filing would be the only way to get the money back
Stating she was exempt on the W-4 from federal tax was correct.
You still claim her as a dependent since she is in school and under the age of 24. you DO NOT report her income on your tax return; if she was required to file (and in this case she isn't) it ONLY goes on her tax return
Be sure to get a copy of HER 1098-T form as that creates the basis for American Opportinities Tax Credit (AOTC) elgibility and could be worth up to $2500 TO YOU
