When will I get my tax bill?

Seems insane I’m WANTING the bill, I know, but I cannot submit my OIC paperwork until I receive it. I filed 3/10. I dont want late fees, so I need to send the 20% of the OIC in by 4/15, I believe, and I want to get this handled before I move overseas.

Who owes for 2024 and received the tax bill? What is the timing of your filing?
