After you file

I knew my taxes were to be offset and the adjusted amount that I would receive. As well as when it supposed to be deposited to my bank account. February 26 2020 has come and gone. I rechecked the where’s my refund tool and it says 0.00 adjusted amount and that my taxes has been offset to satisfy a debt. The amount I was expected to receive is no longer there!! How can that change?? This is so confusing!!! Where did my balance go?
