Wrong billing address

Just to share what I did to resolve this issue. I deleted one of the payment methods associated with the Apple ID. I added it again, changed the auto populated address to the new address then I linked it to Apple Pay. When I went back to iTunes applied.apple.com Payment & Shipping, the address was still greyed out BUT it was the right address.

Thank you for your response. I went to the blue link and instead of go back in the lower left, it's just back in the upper left corner. That closes the screen and brings me back to iTunes. If I go to Appleid.Apple.com and attempt to change it there under Payment & Shipping and then edit payment information, the wrong billing address is there but greyed out where I'm unable to change it.

How do I access the iTunes account on the phone or iPad? So far, I've been unsuccessful. When I open iTunes on the iPad or the phone, it's only a place to buy entertainment. I do not find a place for settings or account management, other than Purchased and My Purchases.

Signing in this way is how I'm able to actually see the incorrect billing address and it being grey and unable to be changed. If I leave these setting and go to the wallet setting, the billing addresses for each payment method are correct. Yet the emailed receipts still have the incorrect address.

I am only able to change the shipping address but the billing address remains greyed out. I tried on the phone and the iPad.
