Before you re-transmit your tax return, change your payment method to “I will mail a check”. That leaves the payment arrangements in your hand. If the credit card charge goes through and is confirmed, then you are done and you won’t be charged twice. If the credit card processor does not confirm the charge, then the pending charge will vanish from your account and you will need to make a separate payment arrangement with the IRS. You can use a direct bank debit or a credit card at www.irs.gov/payments.
