Will Turbo Tax work on a Terminal Server? Would more than 1 user be able to access the same return?

Please do not use TurboTax on a terminal server shared with others. By using TurboTax on a terminal server, one violates TurboTax End User License Agreement (EULA). EULA says:

• Attempt unauthorized access to any other Intuit systems that are not part of the Software; 
