Try this.
Boot computer in Safe Mode with network.
See this link on how to get to Safe Mode with network.

See if you can get TT to work.
If it connects then there is something on your computer that is blocking access to TT.
As for any other tax software that is up to you search for and try.
If you want to stay with a desktop version the do a search for Desktop Tax software.
Please report back as to if the Safe Mode with network works or not.
Edit: Not sure but if you haven't, make any other browser the default browser and see if that works also.
Such as your default is Firefox make Chrome.
Also allow TT popups to work in any of the browsers.
