Why don't I see class when I run Account QuickReport in QBO?

I recognized how important it is to view the correct details when running a report, venu-historic-tr. I'd be delighted to help you sort this out.

Let's customize the Account QuickReport and place a checkmark in the Class and Vendor box. This way, you'll be able to see their columns in the report. 

Here's how:

1. Go to the Accounting menu and then select Chart of Accounts.
2. Locate the account you'd like to run a report.
3. Under the Action column, click Run report.
   
4. Click Customize.
5. Select the correct reporting date.
6. On the Rows/Columns section, click Change columns.
7. Locate the Vendor and Class checkboxes.
8. Then, place a checkmark beside them.
   
9. Once done, click on Run report.

For your visual reference on how the report looks like, I've attached a screenshot below.
