Have a signed power of attorney and contact the IRS.
The IRS will eventually discover their error and will come collecting. The IRS will send out a letter explaining the situation and asking that you pay back the amount of excess refund. If you have already spent the excess, you are still required to pay. Call the IRS immediately to fix the problem. The IRS will collect on the money owed as they would back taxes.
The IRS can put a lien on your home for past due child support and they will even charge interest.

Hire a reputable tax lawyer or tax accountant who can work on your behalf without divulging your identity to the IRS. They can meet with IRS representatives and plead your case, determine the course of action that is in your best interest (possibly reducing or avoiding penalties), negotiate a settlement, and the IRS will not know that they are dealing with you. Then your tax consultant can file the negotiated return on your behalf.
