First make sure your OS is up to date ... uninstalled updates can mess with the system. Reboot the computer to make sure all the updates are installed. 

Here are the recommended installation steps:

You must install using Administrator privilege.

First manually disconnect your computer from the Internet so you can safely temporarily disable your antivirus and firewall software programs.

Close any other open programs.

If installing from a downloaded installation file, then double-click the file to start the install process, and skip the CD steps.

If installing from a CD, insert the CD and the installation should launch.  If it doesn't start installing automatically, then here's how to launch it:

      Hold down the Windows+R keys to open the Run window.
      Click Browse, and then navigate to the TurboTax CD on your CD/DVD/RW drive (usually Drive D).
      Double-click the setup.exe file.
      Click OK to launch the installer.

After installing, be sure to re-enable your antivirus and firewall programs before connecting  your computer back up to the Internet.

Reboot (restart) your computer.

Launch TurboTax and run the program updater.

Taxfile download issues ...  try using another browser like Chrome. 

Thank you for the info- it is not my computer (my computer was serviced and all updates completed a few months after I initial filed because I was having the same issues now as then- it took me over a week and many, many  hours for the filing to finally take) or the browser because I went and used someone else’s computer at their house  yesterday  and the same exact issue occurred. 

Thanks already did that- didn’t resolve issue 

I was able to instantly download several .taxfiles from my test returns without issue so I cannot say why you are having troubles.  Check your browser (clear history) , internet connection and/or  firewall settings. 

Update-After 3 days and 6 hours talking and working with product support… they cannot find out what the issue is. It is a software glitch on their end and they have no idea where or if they can retrieve it.. not good as I need that tax file to amend my taxes for my Schedule D - the file I received the day I did my taxes is not what their system sent over to the IRS- system doubled my counts on my gains and losses. my next stop is to talk to someone in the audit department
