These instructions below that you are describing do not occur.. There is no automatic sync that occurs in google sheets. That exact step is for excel not google sheets.. Maybe do a print screen on that piece of hte instruction where it states auto sync with GOOGLE SHEETS... And every link that everyone sent basically shows EXPORTING TO GOOGLE SHEETS which is not SYNCING.. And the other links are SYNCING with EXCEL... 

1. Follow the prompts to authorize QuickBooks to access your Google Sheets account.

Once you’ve exported the report, you should see an option to enable automatic synchronization. Make sure to turn on the automatic sync feature so that any changes made in QuickBooks Online are reflected in your connected Google Sheet.
