After you file

TurboTax did not use the wrong worksheet or calculations.   TurboTax used the IRS published worksheet calculations that they are require to use according to the IRS e-file provider rules.    It is an IRS "screw-up" not TurboTax.

 

As  said above, as soon as the IRS notified TurboTax (and all other e-file providers - including professional software that had the same error), TurboTax issued an update in May.    If you are using the online versions then it already has the update.   Desktop users need to apply the latest update.
