Mac mailboxes in sidebar
Does anyone know why these mailboxes circled in yellow (see attached image) are showing up here? How do I delete them?

Every account will show up below the unified mailboxes.
If you are specifically asking about "Twc" and don't know what it is, neither do I.
Look in your Internet Accounts to see if it is there. If it is and you don't want it, delete it.
