OS Catalina. 2 MAC HD data drives

After installing Catalina a second time, it put a second Mac HD data partition. Then when trying to use Time Machine, it failed. Because there are two drives with the same name HD data. How do I rename the drive or delete the Drive. How do I know which one Catalina is using?

Disk Utility Shows Two Internal Hard Drives I recently upgraded to Catalina. When checking in Disk Utiliy, it show two hard drives. One called: Macintosh HD; and one called: Macintosh HD - Data. I've read elsewhere that this means that I might be using a beta version, but this is not the case. I've never installed any beta, prototype anything on my MacBook Pro.

I accidentally deleted the Macintosh HD - Data partition while trying to perform clean install Catalina! While I trying to perform a clean install on my Macbook Pro, I accidentally deleted the Macintosh HD - Data partition which is used by new MacOS Catalina. Now, there is only one single partition on my mac and the computer asks me if I want to install the OS on that single partition. I have no idea what should I do or how can I create the Macintosh HD - Data partition again and install Catalina properly.

If I can't get a backup, because the time machine has never had a chance to make a copy, how am I to start fresh?
