Why am I receiving a message from Turbo Tax that schedule H 2021 will not be available until March but it's on the IRS website?

The Schedule H in the TurboTax program must be approved by the IRS before it can be made available within the program.

Schedule H (Form 1040), Household Employment Taxes for 2021 is estimated to be finalized and available in TurboTax on 03/17/2022
