Before I enter my charitable donations, TurboTax says my federal tax due is $80 and my federal tax due is $677.
When I enter my first charitable donation of $10,300, the federal tax due doesn't change, but the Colorado tax due drops to $236.
When I enter my second charitable donation of $1,924, the federal amount stays the same again, and the state tax due drops to $149.
But it's the third charitable donation that confuses me. When I enter that amount ($1,175) , the federal tax due drops to $56 and the state tax due increases to $677.
Does anyone know why the Colorado tax due goes up when I enter my charitable donations?
