The IRS paper form is only the first step.
Once the IRS publishes the paper for then the IRS must use that to develop the electronic form specifications (schema) and then got that to the software vendors like TurboTax. TurboTax must then develop its electronic form to meet those specifications and then submit that back to the IRS for final approval before TurboTax can incorporate the new form into an scheduled update (they usually do not produce an update for any specific form or change or you would have a new update every day.)
That usual means that the update will lag the IRS paper form for 2-4 weeks depending on how fast these processes take at the IRS and TurboTax.
