Delighted to have you here, @Dawn18.

I'd be pleased to help walk you through creating a Budget vs. Actual report by class. 

With QuickBooks Desktop, you have the ability to customize and filter your reports to suit your business needs. Since you've already created budget per class level, here's how to run the report:

1. Go to Reports.
2. Select Reports Center.
3. Choose Budgets & Forecast section. 
4. Click Budget vs. Actual report to run. 
5. Select Profit & Loss by Class, then click Next.
6. Under report layout, choose Account by Class, then click Next.
7. Click Finish.

That should do it! This will get you on the right track generating a Budget vs Actual by Class report.
