There are likely many servers. But there is an uptick in problems like yours tonight. Several users have recently reported such tonight, while other users are connecting as usual without problem, including myself. So there is likely a server or set of servers with problems. You likely will just have to wait until later tonight or try again tomorrow. You could try a different browser, if you have one handy, but others experiencing this tonight said it didn't make a difference.
How are you trying to connect? What type of device? Are you using the mobile app or Online TurboTax with a computer?
