Filed taxes. Can I change method of payment?

[FiguringItOut]

Does anyone know if I filed my taxes and have it set to deduct my payment from my checking account on 4/13, can I change that to be charged to my credit card instead?  Is it too much of a bother? 

I have $3,800 payment going out and if I can change it to credit card, that will cover one of my reward cards for minimum spend.
