Does the 2017 turbo tax program estimated tax function accurately reflect the new 2018 tax law?

Yes, the estimated taxes calculated by TurboTax have been adjusted to reflect the tax law changes and are updated regularly as needed during the season so it is current.

I don’t see where the IRS has updated Form 1040-ES since January 2017. Has TT been able to incorporate the new tax law into its estimated tax calculations for 2018  in the absence of the updated form and instructions?
