Get your taxes done using TurboTax

Changing the Security settings (including turning off firewall entirely) did not work, still seeing Error 2 for the ~50th time.

I am using the installed Desktop edition, TurboTax Premium.  I don't understand all the comments about "uploading" PDF files - I didn't upload anything, TurboTax made all the files for filing. Hence I don't see any way to reduce the size of the file that is internal to TurboTax.

Anyone using Desktop (not browser) found an answer to this, a way to get around the Error?

Today is tax day, and I have been trying to get this working all last evening. I need to get this figured out!
