The report, P&L by Class shows two of payrolls as Unspecified instead of the class. Entries before and since are correct. It seems like a glitch. How do I fix this?

We can rectify the issue with your two paychecks with unspecified classes by reviewing and modifying them, Okie129. Let's work through this together.
 

There are two possible solutions based on the payroll method you're using in your QuickBooks Online (QBO) Payroll. I will outline both scenarios below so you can choose the one that best fits your needs:
 

• If you're using paper checks
  
  1. Go to your Paycheck list.
  2. Customize the date range to August 1 - August 15.
  3. Click the Edit on a paycheck.
  4. Add the class to your paycheck.
   
• If you're using direct deposit checks
  Know that if you need to change the designated classes on a processed direct deposit check, you can edit it directly without needing to add a journal entry. Here's how:
  
  1. Go to Payroll, then Employees.
  2. Choose the Paycheck list.
  3. Look for the direct deposit paycheck you want to edit, then select the paycheck.
  4. Select Edit from the Make Adjustment ▼ dropdown.
  5. Click Edit classes & projects.
  6. Update the classes, then select Save once done.

To verify your modifications, reopen the check and select Transaction Journal.
 

Moreover, you can refer to the section on fixing missing classes in paychecks for additional guidance on the drafted steps in this article: Track payroll expenses by classes and projects in QuickBooks Online Payroll.
 

However, if following the suggested measures does not fix the problem, contacting our QBO Payroll team is recommended. They can address the issue promptly using their secure tools. Details on how and when to contact them are available in this material: Get help with QuickBooks products and services.
 

In addition, if you want to produce a hard copy, email it, or export it to Excel, PDF, or Google Sheets in the future, you can click on these icons above your P&L by Class report or any report:

Thank you for providing additional details and for your patience with this matter, Okie129. The reason you’re not seeing the option at Step 5 to edit the classes directly from the paycheck is likely due to this being a prior payroll. However, you can still correct the assigning of classes by adjusting your Accounting Preferences directly in the Payroll settings. I'm here to walk you through the steps.

By following these steps, we can assign your prior paychecks to their appropriate classes:

1. Log in to your QuickBooks Online company.
2. Click on the Gear icon at the top right corner.
3. Select Payroll Settings.
4. In the Accounting section, click on the pencil icon to edit.
5. Click the pencil icon beside Class Tracking and assign the appropriate classes.
6. Make sure to Save your changes.
7. After updating the accounting preferences, go to Update transactions.  
8. Select the appropriate date range to ensure that these paychecks are now correctly classified in your P&L by class report.
9. Once everything is done, click Save.
