I received an email with a case number and I did not contact intuit

Hello, mchl. Let me help you redirect to the right support.

I would recommend contacting our Customer Care, Support Team. They can verify the case number in a secure environment in which the Community is unable to do so since this is a public forum. 

Here's how to contact them:

1. Go to Help.
2. Select QuickBooks Desktop Help.
3. Click Contact Us.
4. Select Search for something else.
5. Enter "received an email with a case number" in the Tell us more about your question: field.
6. Click Start a Message.

Please know that the Community is always here to help whenever you have any Quickbooks concerns. Have a great day!
