That is because it is an incomplete program and it will not be fully operational until sometime in January or February for some things like states. The program will undergo weekly updates as they complete sections ... this happens every year without exception.
ANY tax software released by any company prior to about January 15 is only released for marketing and market share. No program is complete and ready to file until the IRS approves their final forms and then individually reviews each program's implementation of the form. And some tax situations aren't able to be filed until February or March, again mostly due to IRS delays.
