    erase your Catalina system drive.
    Reinstall/restore your older system. You can do that from the backup that you were certain to make (before installing an early beta on your main boot drive)

    Of course - I can restore from my time Machine Backup - but I need a boot disk don't I?

    I turned off Icloud and it seems to be moving properly now.

    I hope they sort it out in the next release.

    You should be able to boot/erase/reinstall without the need for a local boot disk - just boot to Internet recovery.
    But, it would be a faster method to use a bootable installer for that.

    If your TM backup is to a local drive (like a USB drive), you can option key boot to it and get a recovery screen. From there erase the internal drive and restore from a date that still had the previous OS version.
