I have the same issue, and contacted TurboTax. I spoke with a representative who also was unaware of the situation, and could not help me resolve it. He also did tell me that you are not allowed to file State now without filing Federal and it being accepted. Although I was hoping to at least submit state to get a portion of my refund quicker! He had no idea as far as timeline that the form would be ready, and could not find any info on the IRS site. He suggested I wait until after January 31st to try again...
