My situation may be slightly different. I had been experimenting with TurboTax Free File but was not comfortable with the results and wanted to research further. I received a notice that my order was completed and yet I hadn't agreed to proceed, so I posted a question.
The response suggested I check the following site:
https://turbotax.intuit.com/tax-tools/efile-status-results/
Not sure if this will help you but you might get some insight. Otherwise, it could be a spoof but that would only make sense if someone was trying to get your information when sending the emails.
Hope that helps.
