Can I change the way I would like to pay my federal taxes after I have submitted them via turbo tax?

If your return was accepted, you cannot change your payment method or payment date. But you can cancel the payment and then pay with a different payment method. You can then make your payment here: Paying Your Taxes

Please see the following IRS link for contact information and details: 

IRS Pay Taxes by Electronic Funds Withdrawal - Internal ... under the heading- Cancellations, Errors and Questions for details.

For additional information, please see the following link: When will my tax payment go through?
