Hi there, @accplus-us.

Welcome to the Community family. I can assist you with voiding checks in QuickBooks Online. 

Here's how:

1. Select the Plus icon (+) at the top.
2. Under Vendors, choose Check.
3. The following fields must be completed (the other fields are optional):
   • Bank Account
   • Check #
   • Payment date
   • Account
4. At the bottom, select More and Void.
5. When "Are you sure you want to void this?" prompts, select Yes.

I've attached some screenshots below to visualize the steps:

That should do it.

Please let me know if I can be of additional assistance. I'm always here to help. Have a fantastic weekend!
