Recovery rebate credit was taken for owed back taxes. Will IRS fix this issue?

I received the 1st 2 stimulus payments for myself but not for my kids. I did the recovery rebate and was told I would get $2,200 because I didnt get the money for my dependents. I didnt have any income so the recovery rebate was the only thing I was getting on my return. I didnt even know I owed back taxes and have no clue why but apparently I did and the IRS took all but $36 of my return. How can they garnish the recovery rebate (which is missing money from the stimulus) but not the stimulus? Are they going to fix this somehow? It's so unfair and I'm sure there are several people out there with this issue.
