Hi joan-smith,
Currently, you can only view the Product/Service category in alphabetical order. You'll want to type the first letter to display other choices on the field. I'll also pass this along to our product team to let them know of your business needs.
In case you want to verify for the correct product/services category, here's an article for future reference: Run Reports In QuickBooks Online.
If you have any other concerns about QuickBooks, reach out to us so we can get back to you.
