The online version of TurboTax is shut down permanently and forever for the 2017 tax season. Additionally, the IRS is closed e-filing permanently and forever for the 2017 tax filing season. Your only option is to use the CD version of TurboTax that you physically install on your computer. You can purchase it at https://turbotax.intuit.com/personal-taxes/past-years-products/
If you have already paid for the online product, then you can call TurboTax Telephone Support and get them to put the Cd/Download in your online account. Then you can download the Cd and install it on your computer. While you have them on the phone you can ask your other questions about live support and the such too, and get the answers on that straight from the source. I don't know if live support is continued after the Oct 15 deadline or not.
