No, not if your return has already been efiled and accepted. Once it is accepted the IRS has you return and has started processing. If you sent an installment agreement, they have that too, however if you decide to make the payment in full it will most likely be disregarded because you will not have a balance due. To confirm, call the IRS at 1-800-829-1040. You can also make your payment on the IRS website
www.irs.gov/payments.
