I originally selected that I would mail a check for my balance due, when I efiled my taxes. Now, I would like to pay via credit card. Is that allowed? I assumed it didn't matter as long as they got paid and it was linked to my SSN, but got a weird message that it cannot be changed after the efiling is accepted...not sure if that means via the software or if that's a government rule.
You can use this link for payment options. Unfortunately, you have already efiled so the filing has been sent already
