Here’s my best friend in this whole ordeal. The IRS publishes a PDF each year called the "1040 and 1040-SR Tax and Earned Income Credit Tables" or just the general "Where to File" page.
Go to IRS.gov and search for "Where to file your taxes." It will literally ask for your state and the form you’re filing. It spits out the exact address. You can copy and paste it. It’s the closest thing to a warm hug the IRS website offers.

When in Doubt, Use The Big Two
If you are completely paralyzed by choice, here’s a dirty little secret. Most individual returns (1040) with a payment get sent to one of two main places.
If you live in any of the eastern or central states, you’re likely sending it to Internal Revenue Service, P.O. Box 1303, Charlotte, NC 28201-1303. If you live in western or Pacific states, you’re looking at Internal Revenue Service, P.O. Box 802501, Cincinnati, OH 45280-2501.
Wait, wait, wait. That’s not a rule! It’s a general vibe. Don’t sue me, IRS. Seriously, verify on the website.
