We appreciate you coming back.
I've confirmed that there's an on-going issue with Exporting Payroll Data to Excel in QuickBooks Desktop. While our engineers are still working on this, you can try this recommended workaround.
Run the report from previous quarters, then when asked to update select "Yes." You'll be able to pull all the data correctly. If that does not work, let's fix it by using clean install.
We'll keep you posted once there's an update.
