e-filing with taxes due
I filled out form 4868 extension to file federal return incorrectly, indicating that I owed 0. But I actually did owe and should have paid with the 4868. Had I done this, I would have owed 0.
I am ready to e-file my federal return. Can I make a payment at that time? What about the interest that I owe? Will that stop accruing if I pay the balance in full? Anything else I need to know?
Thanks
