Thanks for sharing a screenshot of your Q, eshorvath1972.

It looks like you're in your Preferences window. Can you tell us what steps you're referring to or followed?

If you're referring to the screenshot in the accepted response, the option to uncheck Don't print items with zero amounts when converting to Invoice is only available in QuickBooks Premier and Enterprise versions. 

You'll want to upgrade your software to either Premier or Enterprise to get the options that you need. Here's an article as a guide: Upgrade QuickBooks Desktop Pro Plus, Premier Plus, or Enterprise.

If you're referring to the last steps in the thread, let's exit and open the invoice to make the changes to the template. Here's how:

1. Open the invoice of the customer.
2. Go directly to the Formatting tab.
3. Select Customize Data Layout.
4. Proceed to the Footer tab and check the box next to Balance Due.
5. Click OK.

Let me share this article with you for extra guidance and references: Fix Common Issues When You Use and Customize Templates.
