If I work jobs in 2023 one job I made 1400 the other one I made 1200 and the last one I made just $15,6 00 how much will I get back in time

No way to know.  Depends on a lot of things.  Like your tax status Single or Married and how much federal withholding was taken out at each job.   Did they take out taxes out of all jobs?  If a job didn't withhold anything they may have paid you as an independent contractor.

You have not provided enough information.   We do not know if you will file as single or married; we do not know if you have any qualified children to claim as dependents; we do not know if you will receive W-2's for those jobs and how much tax was withheld by the employers, or if you worked as an independent contractor with no tax withheld.....etc., etc., etc.
