I'm confused, too.
So, did you owe money on the original return, or get a refund?
So, did you owe money on the amended return, or get a refund?
"Original tax return, I owe the money to the IRS, but I have paid already in 2022. What should I do in this case?"
Hey, don't worry about where to mail your payment, just go to the IRS webpage "Make a payment". You can pay online for original returns, amendments, and all sorts of things, and you don't have to worry about the address.
The only thing is that you may have to wander around a bit at the website to find what you want.
