Hi, Fluteteacher-missreed. This error can happen if you purchased the subscription through a third-party app, such as iTunes or Google Play, rather than directly on the Intuit website.
Based on your scenario, it appears that you have already used the app before, but now you're experiencing this error while logging in to your mobile app. If this is the case, I recommend contacting our Live Support team to investigate the root cause of the error and provide the steps on what to do next. Here's how to reach them:
- Go to our Contact Us page.
- Choose your QuickBooks product under the Which product is your question about dropdown.
- Type in your question or concern, then click Continue.

- Put your login credentials, then Sign in.
- Select the Callback option.
You can also check this article if you want to know our support hours for different subscriptions or products in QuickBooks: How to get help with QuickBooks.
We're here if anything else comes up.
