It's good you're you're using the location feature in QuickBooks. I'll be happy to show you how to filter your P&L by location.
To do this, click Reports from the left menu and open the Profit and Loss. Once you've done this, click on Customize > Filter > search for your class > Run report. I encourage you to check out this article with more info on customizing reports in QuickBooks: Customize your reports in QuickBooks Online.
