Welcome, @bevr. I've got ways on how you can void a check in QuickBooks, and I'll show you how.

If you're referring to QuickBooks Desktop 2004, this version is already unsupported. This is because Windows 10 or later is no longer one of the supported Operating Systems. With this, you'll be unable to get the best Desktop experience.

In line with this, you will no longer have access to the software's Payroll Services, Payment Processing, Live Support, Online Backup, Online Banking, Technical Support, and other services. You can read about QuickBooks Desktop service discontinuation policy and upgrade information to learn more.

However, if you're not using any of the add-on services, you can still continue working in the program. This means we can void any transactions from your bank register. Please know that this might affect your past financial records.

Here's how:

1. Go to the Banking menu, then select Use Register.
2. Select which account you saved the check.
3. Locate the check and double click.
4. On the check window, press the Delete dropdown and tap Void.

I've added some screenshots below for your reference:

Feel free to scan through this guide about checks: Create, modify, and print checks.

If you'd like to upgrade your company file, it should be in 3 years gap version at a time. For instance, you'll upgrade your file to 2007, 2010, 2013, and so on. This ensures that the software is compatible with your computer to get the best experience in using the program.
