After you file

I understand what amending is and I have read through all the articles and watched the videos.  The problem is that the drop down menu that should be available online is not there.  

I have also asked for a callback, but instead the autobots sent me a canned email response that says this:

To amend a business return, you will need to download a copy of TurboTax Business Desktop. Since you have already purchased the online version, you do not need to pay again for the desktop version for the year you need to amend

I have tried to find a place that will allow me to download a copy without being charged, but that is elusive.  

Anyone have a way to find this desktop version?
