You've come to the right place for assistance, Windy. Let me ensure you're able to get the help you need about your payroll summary by class report.

With QuickBooks Desktop Payroll, all information entered when setting up your payroll will depend on the data on how you've set up your employee's payroll. As of the moment, we haven't received any reports relating to your concern. With that, I'd suggest reviewing them from the payroll center and verifying all the details entered accurately.

If the same thing happens, this might have caused data damage to your company file. Let's run the Verify Rebuild Data tool to help us identify and ensure payroll summary by class will reflect when running the report. Let us first ensure your QuickBooks Desktop is up-to-date. This way, you'll always have its latest features and fixes.

To verify the data:

1. On the top menu, click File and select Utilities.
2. Click on Verify Data.
3. Select OK when QuickBooks doesn't detect any problem with your data.
4. If Verify finds an issue with your data, you'll be prompted to Rebuild Now or View Errors.
5. Click Close or View Errors and take note of the specific error message.

Next, here's how to rebuild data:

1. On the top menu, click File and choose Utilities.
2. Click OK if you receive a prompt to back up your company file.
3. Select OK when the rebuild is complete.
4. You can run the Rebuild Data again to ensure there's no error.
