How do I find out exactly where my past tax returns have gone?

The IRS says I owe $837 from 2021 but I have filed my taxes every year, was supposed to get a refund for the last 2 years, and never got one. I assumed they were paying off this debt. I checked the IRS website and they don't show any notices saying it went towards any debts. They don't really show much info period. I know there is a number I can call. I want to find out exactly what my tax returns were for state/federal since 2022 and I want to know exactly where this money went, if not this debt. Is calling this number going to get me that info?
