All apple devices keep saying Update Apple ID Settings
I updated my Late 2015 iMac to Catalina and wanted to try Sidecar. It was not appearing and after some research I read something about 2FA needed to be enabled for it to work. I enabled it and now my Mac, iPad, and iPhone and possible more devices are telling me to "Update Apple ID Settings". I have entered my Password multiple times but it won't go away. I have also signed out and back in to iCloud but no avail. What do I need to do to fix it? I have attached an image with personal information blurred out.
