Hi, unfortunately, these directions (see below)  did not help because an "Old Layout button" was not available in my QB online Essentials. 

If you are on the Essentials or Plus plan, you can revert to the old interface by following these steps:

1. On the left navigational bar, click the +New button.
2. Select Invoice.
3. On the top-right corner, click the Old layout button.
4. Click the Switch layout button.
5. Enter or select the necessary details, and then the click Leave and submit button.
