You appear to be using Online TurboTax. If you're asking in regards to Online TurboTax, the website for a new tax year normally opens up the first week of December, plus or minus.

The program will undergo updates over the first few weeks while IRS forms are finalized and the software tweaked. The last couple of years there were significant late tax law changes which required additional programming and form revisions, and there could be the same this year.
