Thanks for your reply. These links have confirmed that I just have the one TurboTax account. I've had this account since I was last living in the US almost a decade ago, but even after searching through my email, I can confirm I have never gotten an email to this effect -- which leads me to believe it's linked to the fact that I started the return earlier. I know I started a return a few months ago, and I don't understand why suddenly it has disappeared...
