Apple file system in macOS Catalina made some changes, it separates user data and system data on the startup disk with two different volume. If you open the Disk Utility.app, you will see the Macintosh HD and Macintosh HD Data volumes. Macintosh HD is a read-only system volume, and all your files and data are stored in Macintosh HD Data volume, two separate volumes are created during the macOS Catalina upgrade process, some files and data that you previously stored in the startup volume need to moved to anther volume.
Some files will be moved to a Relocated Items folder, and the Relocated Items folder is in the Shared folder within the User folder: /Users/Shared/Relocated Items.
