How can I change the date of the last payroll checks? They were recorded incorrectly.

Hi there, @insinu8.

Having an accurate date in payroll checks is a way to ensure you've paid your employee on time. However, in QuickBooks Online (QBO) the option to change the pay period of checks is unavailable. As a workaround, you can delete and recreate the paycheck with the correct date. Follow along below to get this done right away:

1. Navigate to the Workers menu, then click Employees.
2. Select Paycheck List under Run Payroll,
3. Change the date range if necessary. Then choose the paychecks you want to delete.
4. Click Delete.
5. Mark the checkmark box to confirm the deletion. Then, Delete Paycheck.
6. Once done, recreate the paycheck with the correct date. 

For your reference, you can visit this article: Change or edit paycheck date.

Also, QuickBooks makes it easy to view your employee data and monitor your business finances. To get started, you can open any payroll reports you need. To give you a list of those reports and an overview of what data they show, please head to the Run payroll reports page. 

Don't hesitate to post again here whenever you have concerns about editing your payroll checks in QBO. It will be my pleasure to assist you always. Have a good one.
