I am having the exact same problem with Wisconsin efile and did not get any help from TurboTax support. She suggested I keep trying every few days in the hope that "they" fix the problem. As I understand it, "they" meant the state of Wisconsin rather than Turbotax as my customer support person did not feel a need to complete a problem ticket or to forward my problem to anyone beyond her. She had also suggested I file the return through regular mail even though we both read on a Turbotax screen that it was mandatory to file via efile. At another point, she suggested I couldn't efile because I was going to make estimated tax payments which was also not my situation. Totally unsatisfactory customer service, especially for a program that is a little pricey and purchased by me primarily for the efile function. Not sure what to do if "they" dont' resolve this issue before the filing deadline.
