The IRS already had a method in place ... has for years ... once you have successfully filed Turbotax is no longer involved so expect no help from them ...
- Once your return is accepted, information pertaining to your payment, such as account information, payment date, or amount, cannot be changed. If changes are needed, the only option is to cancel the payment and choose another payment method.

- Cancellation requests must be received no later than 11:59 p.m. ET two business days prior to the scheduled payment date.
