clearing/removing calendar profiles

So, I have a Google Gmail account that was upgraded to GSuite (using the same email address). Since I previously synced my Thunderbird Calendar with the Gmail version, if I remove that calendar and try to create a new one, Thunderbird does not see my new GSuite version, it retains the calendar account info for the Gmail version. I have reviewed the forums and tried to delete my storage.sdb profile file to remove all calendars, but my calendars are still present when I relaunch and the file is recreated, so deleting it did not help. Essentially I want to remove all calendars and start over without having to reinstall Thunderbird itself so that when I try to reconnect my Gsuite calendar its not referencing the older gmail version. Any advice is appreciated. Thanks!
