Where is IDNotify? I click the link in the notification email - it goes to a sign-in page that leads to tax prep workflow, no links to IDNotify anywhere.

When signed in, the link STILL takes me to another sign-in page. Searching, the help articles say "click the link in the notification email." Well, that doesn't work. Searching all the Intuit sites doesn't work. Signing into TurboTax just forces me into tax prep workflow. Why is this garbage service mandatory, and completely unusable?
