Hey there, Dennis Home.

As mentioned by my colleagues above, the Not Specified column in the report indicates when a transaction does not have a payee or customer assigned.

To correct this, we can open each transaction and ensure that it has a customer assigned to it. Here's how:
 

1. From your Profit and Loss report screen, click on the dollar amount in the Not Specified section.
2. Then, open each transaction and make sure they're associated with a customer.
3. Once you're done, hit on Save and close.

However, if you're still seeing the Not Specified section in the report, let's assign a class to your employees. See the steps below:

1. Click the Gear icon at the upper right corner and choose Payroll Settings.
   
2. Go to the Preferences section.
   
3. From the Accounting Preferences, scroll down to the Classes section.
4. Choose I use different classes for different employees option.
5. Tap OK.
   
6. Assign a Class for each employee by clicking the drop-down arrow.
7. Select a Class from the List.
8. Hit OK.
   

This should get you on the right track. I'll be leaving you the links below. These will provide us with more information on how class tracking works as well as tips on how to manage your payroll preferences in QuickBooks Online:
