No one claimed me and I filed my return bc I never received a stimulus. Now IRS states they adjusted my refund to 0, but their reasons don't match any of my situations.

I called a TT expert and they instructed me to file my own return instead of having my BF claim me under HOH. I claimed my college tuition and didn't pay any taxes. After 5 months I finally have an updated status that says IRS reduced my refund to 0.00. They gave reasons that SSN is incorrect, but it is not, it states qualifying dependent info does not match, but there were none to begin with, I didn't exceed the income amount and the amount was calculated incorrectly. I'm at a loss on trying to understand what was wrong so if anyone might have some ideas it would be greatly appreciated.
