login to your turbotax, on the upper (way on the top) left hand side look for Turbotax, and click on turbo tax, the drop down menu would show a lift of links. One of the links (third one down the drop down menu) is check for updates. Click on the link and you will be directed to update and install. Takes a while to download and implement the update. This step fixed my date failed validation issue during efile. Good luck.
