How do I toggle back to desktop version which I was using yesterday

Welcome to the Community, llothrop-sbcglob.

If you're referring to our QuickBooks desktop app, you can download a copy while signed in.

Here's how:
 

1. Use your Gear icon, then go to Get the desktop app.
2. Depending on your settings, you might see it install automatically. If not, QuickBooks will prompt you to save the .exe file, then you can run it manually.
3. A shortcut to your app will be created on the desktop. After you've finished installing it, it should open automatically. If it doesn't, you can use your desktop shortcut.
4. On the sign-in screen, enter your user ID and password, then click Sign in.
5. In the event you see multiple companies, choose one to open.
6. When asked to decide how QuickBooks is displayed on your homepage, select Yes, let's go for a similar view to QuickBooks Desktop, or No, I already know how to use QuickBooks Online.

If you're already using the desktop app, you may be referring to switching views in it. You can find detailed information about changing your view in our Use the desktop app article.

I'll be here to help if there's any additional questions. Have a wonderful Friday!
