Refund

I filed my taxes in March of 2021 for 2020.  My sole means of income was 30K in UI Benefits that I did pay taxes on.  Then came the Tax Credit meaning that I should have only paid taxes on 10,200.   Will I get the additional taxes I paid back as a refund?   Is there anything else I need to do on my end with the IRS?  Or, will this happen automatically?
