Hi there, @Anonymous.

Thank you for getting back to the Community and for sharing more details about your question. I'll be happy help share the steps to make sure the Toolbar is in place.

Here's how: 

1. Select QuickBooks.
2. Choose Preferences.
3. On the Preferences pane, select Toolbar.
4. Put a check mark in the Display Toolbar box.
5. The second checkbox refers to whether you can see the Toolbar even when QuickBooks is a background application.
6. Close the Preferences window.

I've attached an article about QuickBooks Mac 2019 for additional reference: QuickBooks Desktop for Mac 2019 User’s Guide (Toolbar preferences page 270).

That should point you in the right direction today. Keep me posted if you have any other question about toolbar location in QuickBooks. I'll be happy to help you further. Have a great day ahead.
