Level 15

As noted, we are end users and not customer support. I found this article:

https://proconnect.intuit.com/support/en-us/help-article/form-w-2/clients-use-intuit-link-send-reque...

And this user topic:

https://proconnect.intuit.com/community/proseries-tax-discussions/discussion/client-with-existing-in...

That sort of explain username vs email vs link ID. Hope that helps.
