Hello Korytchenko,
Thanks for using Apple Support Communities! I see you've got an unusual issue with macOS Catalina and I'd like to help you get the assistance needed.
With macOS Catalina, you will see two Macintosh HD drives, one which will be "Data", as shown here: About Disk Utility on Mac
However, having a duplicate "Data" drive is not expected, and looks to be why Time Machine is giving you that error.
I'd recommend contacting Apple Support so they take a further look at what could have happened.
Enjoy your day!
