In addition TurboTax (and other tax software companies) do not program from forms, they program from schemas which are the electronic file specifications that must be transmitted to the IRS in a format that the IRS computer can read and understand. The "form" that you see in TurboTax is only for the data entry screen, but the data itself must be encoded according to the schema to be transmitted to the IRS. It usually takes the IRS 2-3 weeks after the final paper forms are issued to release the schema for that form. Then, as previously stated, the IRS must approve the TurboTax implementation before it can be released to the public.
