TurboTax just released an update which resolved the issue for me. TurboTax Desktop now imports through my VPN. So, the solution is to update TT the next time you start it.
One minor issue is that Google reCAPTCHA gets annoyed when so many people share IP addresses through a VPN. ReCAPTCHA throws an error message:
computer-or-network-may-be-sending-automated-queries, which you can expand to:
You could get this message if others that use the same Virtual Private Network (VPN) you use are sending automated searches to Google.
Some VPNs and tunnel services cause all traffic to be blocked because they make it impossible for Google to tell the difference between abusive and non-abusive traffic.
After I waited, I tried again. I received the most difficult CAPTCHA puzzles I have ever seen. They finally accepted me. Then TTD imported through the VPN.
Update your OS. Update TurboTax. Be patient with Google reCAPTCHA. Then success will hopefully be yours.
