I am also wondering about this! However, for me, I don't have the potential explanation - the number I see for state and local income taxes or general sales tax doesn't match what I paid/owed in state taxes for 2020 or 2019 as far as I can tell. But it doesn't make sense that it'd be general sales tax either - I didn't tell turbo tax anything about how much money I spent. That would be a prerequisite to it computing sales tax, right? Or does it make an estimate based on your income, or something like that?
