Okay, I finally got in.  Apparently I used a different email address when I purchased the subscription to the latest version.  I don't understand why the email address for the account would be different than the one Intuit uses to contact me.  

BTW, I cleared cache and cookies in both Edge and Chrome, and also tried incognito mode in each, but the "Claim Account" option never appeared.

Anyway, I'm in now. Thanks.
