Hi Cynthiad66, thank you for your reply. I've already read all that after several hours of searching around, and none of that is relevant to me. I've already done all that long before I installed Turbotax and I have an IT background. The solution for me, after digging around in firewall seems that TurboTax software needed outbound access to an IP internet address that falls in the range of 192.229.0.0 thru 192.229.255.255. Some of that domain range is registered possibly to "EdgeCast Inc." which I'm assuming is ISP provider for Intuit et al. Not sure but allowed the software to load the intuit login interface and then ask for the license key. Hope that is helpful for someone else.
