I solved this by updating firewall rules to allow outgoing traffic from the executable. In Windows Defender, Outbound Rules, New Rule:
Program
Add program path, usually something like C:\Program Files (x86)\TurboTax\Premier 2019\32bit\TurboTax.exe, you will have to check your own drive
Allow the connection
Private (Domain if you are connecting from a Windows domain, like a company network)
There is nothing to change back when you are finished. This is a permanent rule.
