The default location under macOS is:
/Users/username/.local/share/Manager, where username is your own user name.
Note that this is a hidden file. Hidden files can be toggled on and off by typing CMD + SHIFT + . simultaneously while in the Finder. (That’s a period at the end of the combination. This is a macOS function, not a Manager function.)
Be sure you have read and understand the Guide at Move desktop application data to another folder | Manager. This is the original Guide on the subject and is not yet covered by the new Guides.
Depending on how your application data folder location was changed from the default, you may see the Reset button pictured in the Guide and be able to simply click it. (Based on your screen shot, this is the case.) Note especially the comments about how changing the location does not alter or move data. You are only altering a pointer. After you change the location, you can copy and move data from your Google Drive.
