I need to change the way I pay my taxes from mailing in payment to drafting from my account. I didn't realize I had filed that way. My return has already been accepted.

You would not be able to update it with TurboTax but you can make a direct payment to the IRS here - https://www.irs.gov/payments

If it is your state payment please see your state Department of Revenue website -
