Two different Macintosh drives are there

I recently upgraded to Catalina, and after upgrading to it, my storage is full now, and theres a new partition 'Macintosh HD' which is using 10gb of storage.

This is normal for Catalina. macOS Catalina is the first Macintosh OS to create two separate volumes for the operating system files and your data files.

I really wouldn't try and mess around with or delete one of the volumes.

That is normal for Catalina. One drive is read-only and reserved for the operating system. The other is for 3rd party software and your own data. In theory, software shouldn’t notice the difference.
