Thanks for posting your question here in the Community, beccajacob.

I'd be glad to show you how to use class tracking in your QuickBooks Desktop account.

1. Click the Edit tab in the top menu bar.

2. Select the Accounting preferences.

3. Choose the Company Preferences tab.

4. Check the box to Use class tracking for transactions.

5. Select the OK button.

6. Choose Lists from the menu bar and then Class List to set up class categories for your expenses and accounts.

7. Click the arrow next to the Class button at the bottom of the page.

8. Select New to create a new class.

9. Enter the name associated with the class.

With this info you'll be able to assign class codes to your accounts. The following article provides even more details about using this feature: https://quickbooks.intuit.com/blog/whats-new/how-to-use-class-tracking-in-quickbooks/.

I'm only a comment or post away if you have any other questions. Take care!
