Hey Wendy! Welcome to the QuickBooks Community! I'm excited to help you manage your scheduled reports in QuickBooks Online.  Here's how:

1. Login to your QuickBooks Online and click on Reports from the left-hand menu.
2. In the Reports section, click on the Custom Reports tab. This is where all the reports you've customized and scheduled are stored.
3. Edit Scheduled Reports:
   
   1. To modify an existing scheduled report, simply click on the name of the report you're interested in. This will open it and you can make your changes, including adjusting filters, date ranges, and formats.
   2. Don't forget to Save your changes.
4. Delete Scheduled Reports:
   1. If you need to remove a report from your scheduled list, under Actions, click on Delete.

That should do it! And as always, please feel free to loop back in the thread if you need additional assistance. I'll be available to back you up anytime.
