Hi there, @OfficeLadyAnne.

Thank you for reaching out to us. I'd be glad to help you fix any possible sign-in issue on your account.

I recommend you update your QuickBooks release version to avoid getting emails that you haven’t signed in to your Intuit account for over 180 days.

Let me show you how:

1. Open QuickBooks. Then go to Help.
2. Select the Update QuickBooks option.
3. Click on the Update Now tab.
4. Mark check on the Reset Update tab to erase all the previously downloaded updates.
5. Select Get Updates.

Feel free to read this article for the detailed steps in installing QuickBooks: Install QuickBooks Desktop.

You can always leave a comment. Have a great day!
