Voided paychecks can not be directly reversed within your QuickBooks Online (QBO), Casa. This also creates an adjustment entry to balance your books. 

In this case, you can reach out to our Live Support Team, as they are equipped with tools that can handle voided payroll checks. Here's how:

1. Sign in to your QuickBooks Online account.
2. Click the Help (?) icon.
3. Go to the Search tab, and click the Contact Us button.
4. Type your concern into the What can we help you with? field.
5. Click Continue and choose a way to connect: either Chat with us or Schedule an appointment.

You may also want to check their support hours to reach them at a convenient time.

Another option is to recreate these checks by referring to the details from the previous one.

If you have any additional questions about QuickBooks, don't hesitate to reply. We're here to support you 24/7.
