I understand the importance of having the product description visible when entering a product or service in QuickBooks Online, @Forest2125. Rest assured, I'm here to provide you with the necessary information and assist you in creating invoices seamlessly with the new layout. Let's work together to find a solution to this issue.

Old and new invoice layouts are two different experiences of QuickBooks Online that offer almost similar uses and features. 

To name the features that are unavailable in the new layout:

• Ship via, Shipping date, and Tracking no. fields
• Adding a new invoice Term
• Send Later option
• Print Later option
• Reference links displaying matched online transactions
• Subtotals
• Account Summary
• Price Rules

With that being said, the description of the products should still show. However, in the new invoice layout, you have to select the product first so its description will appear in the Description column. Please see the screenshot below for your reference:

On the other hand, if the products still won't show even if you selected them, I'd suggest using a private browser to see if this is caused by your browser's cached files. Use these shortcuts to access incognito mode:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P
• Safari: Command + Shift + N

Once the description appears, go back to your regular browser and clear its cache. This is done to speed up the process next time you do a transaction in QuickBooks Online. Also, an alternative way is to use other compatible browsers.
