2021 tax software installation issues

[carangreg]

I have purchased the 2021 Turbo Tax software and have tried installing it on two different computers, one running Windows 10 and the other running Windows 11.  It is unable to determine that the computers are connected to the internet and therefore unable to authenticate (even using the alternate authentication method offered in the installation process).  

Is this a known issue?  What is the solution?  I purchased this software and am unable to use it.

Do you have a firewall or any anti-virus/anti-malware that might be blocking TurboTax Desktop from connecting to the internet? If so you may need to change the settings to allow TurboTax to connect, or even temporarily disable the security software/firewall to allow you to authenticate. 

If you are still not able to resolve this issue, please contact our phone support team for more assistance.
