Calendar invite is autofilling old addresses on Mac mini running Sequoia 15.5

Need some help from someone who has been able to tackle this. I want to remove my wife's old company work address that she no longer has from autofilling when sending a calendar invite. I do connect my google contacts to my account, but that shouldn't be an issue.

How do I delete a previous used invitee a… - Apple Community

The address was removed from my contacts several years ago, and it's nowhere to be found either in my google account or my apple account, contacts or email. I've removed recent invites, in calendar, it's not in safari autofill. Nothing seems to work and it's driving me insane.

Working on a mac mini sequoia 15.5. Thanks
