I am trying to e-file an extension using my TT account, and every time I am going there to start e-filing an extension, it says as below - Am I doing something wrong? Or this is not yet available?

If this e-file TT easy extension thing is not available based on the error I am getting then by what date it will be available to use?

Second question:

When e-filing an extension using TT, will TT allow me to pay taxes owed during extension e-filing process? If yes, then what "ALL" payment methods will TT accept during the payment of taxes owed during an e-filing of extension process, please let me know asap, thanks as I want to use ONLY TT for paying owed taxes using credit card instead of going to IRS website and paying from there. Thanks.
