If you're referring to a check record in QuickBooks, you can edit it to make any necessary changes.
Here's how:
- In your left navigation bar, go to Expenses.
- Find the check and use its View/Edit option.
- While editing your check, enter an appropriate Check no..
- Make any other necessary changes.
- Select Save and close.
In the event you're referring to something outside of QuickBooks, in an account with a third party company, I'd recommend getting in touch with their support team for assistance on how to remove check numbers from payments.
I've also included a detailed resource about working with checks which may come in handy moving forward: How to view & edit vendor transactions
