i am doing my 2024 income tax form on turbotax, and want to know what "form" or "schedule" shows the math of the income tax

you know, it would appear it should be easy to plug in a number for federal tax, married filing jointly, and come up with an answer - some "calculators" are way off - is there a "form" or "schedule" in my turbotax printouts that show "the math" ?????
