What TurboTax does has nothing to do with what the IRS is doing. Once your e-filed tax return has been accepted by the IRS, there is no further communication between TurboTax and the IRS. TurboTax does not get any feedback from the IRS, and the IRS does not get any further input from TurboTax. TurboTax updated the tax calculation on its web site. The IRS doesn't know that TurboTax did that, and the IRS was not involved in the update. The update in TurboTax doesn't tell you anything about what the IRS is doing.
