I'm happy that you've reached out to us for your payroll liability concern, @ap-pre-employ.

Based on the error that you've received, it indicates that the scheduled liability payments were not processed due to missing information. To fix this, I recommend running the Payroll Liability Balances report. This way, you'll be able to check on the liabilities manually and see which entry contains missing details.

To do that:

1. Click on Employees at the top and choose Employee Center.
2. Refer to the Payroll tab and click Pay Liabilities. 
3. At the bottom of the page, press on Payroll Liability Balances under Report. 

From there, you may manually check on each liability check for the specific period where you received the error message. In this case, you'll be able to verify the transaction that causes the error and add the missing information.

You can also view the check directly from the Transactions section on the Employee Center page. Just make sure to select the right date range. Please see the screenshot attached for your reference: 

Moreover, the system doesn't contain the Related Payment Activities button to see the payments, which contain incorrect details. The steps that I've shared above are the best way to look for the scheduled liability payment the error is referring to.

Lastly, you can always read through this link, which provides more insights about managing payroll liabilities in QuickBooks Desktop: Set up and pay scheduled or custom (unscheduled) liabilities.
