Be careful.
If you enrolled in IDNotify when you paid for turbotax (it's an extra fee), then you need to log into your IDNotify account to see any alerts, not your Turbotax account. Turbotax only does taxes, not ID protection.
If you are concerned about the email, log directly into your IDNotify account after making sure you see a padlock icon in your web browser's address window. Don't click on links in the email itself.

I have the same thing. Says my email was found on the dark web. It said I should sign in. There is a video to watch but it won't let me watch it. Does anyone know if this is real?
