I can see the urgency to have your payroll checks fixed as soon as possible to get you back in working order,  HomerFair. I've got you covered. 

The option to merge the payroll information is not possible. This is why you're getting an error " You cannot modify the employee on a paycheck." Not unless you delete all of them. However, it is important to note that deleting the paychecks in your records, particularly the liability account.

I suggest contacting our Customer Care Team. This is to ensure the accuracy of your records and to avoid creating discrepancies in reconciliation and taxes.

Here's how to reach them:

1. Open QuickBooks Desktop.
2. Go to the Help menu, then select QuickBooks Desktop Help.
3. Click Contact Us at the bottom.
4. Enter a brief description of your issue, then select Let's Talk.
5. Choose a way to connect
