After you file

Hi.  I understand that TurboTax won't have the 1040-X for 2021 available until March 17th.  I recalculated my taxes owed, and cancelled my scheduled payment.  When I do the 1040-X will TurboTax allow me to make my payment directly from TurboTax, or do I have to go to the IRS Direct Pay website to pay the correct amount?  Also, how will TurboTax know I just cancelled my scheduled payment today?  (This is the first time I have to do an amended return, and hopefully, the last).  Thanks.
