Text forwarding on Mac

I have an iPhone 11 and I am trying to turn on text forwarding on my iPhone so I may send and receive messages from both my Mac and iPhone. I have two appleIDs and I accidentally turned on text message forwarding on the one I don’t currently use anymore and for some reason can no longer turn it on The id I want to use. I have tried restarting both devices and re logging in but nothing seems to work. The text forwarding option never shows up on the account I’m actually trying to use Yet it always appears on my other account. I have tried disabling iMessage and turning off text forwarding on the account in no longer using but the option is still not showing up on my current account. What can I do to enable the Text message forwarding prompt to appear on the account I want to link it to instead of my old one?
