Same issue on a Windows 10 workstation. The first set of forms (federal, state) worked fine prior to the latest updates. A recent new return forced a Turbotax update to the desktop installation, which broke the ability to transmit forms to either Fed or State. Doing a reinstall of the software from CD didn't resolve the issue. Attempted to call/contact Intuit support which only brought me here to complain about the buggy software. The only silver lining is that I saved transmitting fees to the State. You lost revenue Intuit, and probably a customer with the poor technical support.
