@proreflexology10 there's an acronym for this. GIGO - Garbage In Garbage Out which means the correct results depend on correctly and completely entering all relevant data. People omit things like the economic impact payments or the advanced childcare credit they already got. then their return shows a big refund which the IRS computers change to reflect what actually took place based on its records. other taxpayers' omissions because they want to file ASAP before they have all their tax documents include omitting W-2s and 1099s.
