How does one big beautiful bill act actually affect me

I seem to be getting a different answer depending on who I ask. I'm mainly curious how the no tax on overtime is actually going to look because I realize it's a tax deduction not a dollar for $1 thing however if I get paid $45,000 a year but my overtime brings me up to 100,000 a year then where would my filing status land because in my mind it would mean that I would still be at the $45,000 mark and not the 100,000 mark but I'm being told that's not the case.
