right now do nothing. it would likely make matters worse. hopefully, the IRS and state will see that your account with them is overpaid and automatically make a refund. as a pure guess this could take 6 months. so be patient. if you don't get the refund by then you'll need to call. this may take multiple attempts with the IRS - too few agents to handle the too many calls. before calling make sure to have all documentation handy. this would include copies of the front and back of any checks that were used to make payments, credit card statements, etc.
