I amended my 2021 return and e-filed the amended return in Turbotax. Will the IRS auto-deduct the amount, or will I need to send a check?

We got an IRS letter saying they saw an error and stated the amount (and interest) we owe.  During the amending session in TurboTax I saw a message stating the amount owed would be deducted, but it didn't come up again.  Moreover, it never asked the amount to be deducted (I owe interest too).  Trying to understand if I need to initiate the payment or will Turbotax do it (or the IRS).
