Joining the thread to offer help, @Whoadeb. I wanted to ensure you're able to use the customer and class column while writing a check.

In QuickBooks Desktop, the CUSTOMER:JOB column while writing a check is a system design as part of the program. While the CLASS column is a feature that needs to be turned on. I'll show you how.

1. Go to Edit.
2. Select Preferences.
3. Click Accounting.
4. On the Class section under Preferences, put a checkmark on the Use class tracking for transactions selection.
5. Below the Assign classes to menu, choose Items.
6. Click OK.

However, if both columns are not showing while writing a check, right-click on any row on the items of your check. Then, a new window will show up having you the option to select and customize columns.
