TurboTax does not process the payment of your tax due. In fact, TurboTax never knows when, how or even if you paid your tax due. You can enter the information into the software for a payment to be made to the IRS, but the IRS processes that payment--not TurboTax.
The IRS is backlogged due to the pandemic, so you will simply have to watch your account and see when they take out the payment. TurboTax has no control at all.
