The TurboTax software for the desktop CD/Download editions for 2019 should be available in mid-November of 2019. The TurboTax web based online editions for 2019 should be available sometime in December of 2019.
The desktop software and the online software is basically the same software so how fast or slow is based on either your internet speed or the processor and amount of memory on your personal computer.
You can access the online editions with a Windows 7 based computer.
Since Microsoft is discontinuing support for Windows 7 in January of 2020, TurboTax will not support the TurboTax 2019 software installed on a Windows 7 personal computer.
