I am finished with my S Corp tax returns, and was able to transmit my federal return without a problem. However when attempting to transmit my State return (WI), I get the following pop-up message: "There is an update available for your version of Turbotax. Before you can file electronically you'll need to get this update. To do this, go to the Online menu and select Check for Updates." Well, I've done this a hundred times, and the same message keeps popping up. I've called TT and been on the phone with them for several hours and no one can figure it out. I do not have the option of filing by mail, as WI will only accept this return electronically. I'm stuck, please help!
