Hi, @dmangolas.
I'm here to help you get back to running your business. It's a very smooth and easy process to find the option. Here's how:
1. Open QuickBooks.
2. Go to Edit
3. Select Preferences.
4. Choose General.
5. Click Company Preferences.
6. Checkmark the box beside of Always show years as 4 digits (1999).
That's it! This is a link that can give you more information about printing checks.
I'm only a post away if you have any other questions. Happy Wednesday!
