Has Turbo processed the tax payment for the due amount? while preparing return, I was asked to provide bank details to make the payment to IRS but I don't see any debit

The debit info was sent with your return and it is the FED's or STATE's responsibility to process the payment which can take a few days this close to the end of the filing season.   If the return has been ACCEPTED for processing then watch your bank/CC account to see when the payment posts.  

TurboTax will never know if you paid your taxes.  Your TT account will always show that the result of the return you prepared showed that you owed.  The IRS/state do not tell TT if you paid.  Your proof that you paid will be your own bank/credit card records.
