Deductions & credits

Thank you. I actually just sent $500 and would owe them just about another $,1500. When I mailed my amended form in I sent that check and indicated I would set up a repayment plan when they processed my amended return. Thanks to the stimulus check I’ll be able to pay them back immediately, but at this point I don’t think there is a way for me to pay the difference until they process the amendment. Is there?
