No. There's none. Your 2020 income tax retund can be taken to offset prior federal debts such as student loan, back taxes, child support, and other federal debts.. You should also receive a notice of explanation from the IRS why the money was withheld.
Under the CARES ACT (EIP 1), your entire Economic Impact Payment authorized by the CARES Act, can be offset, up to the amount of your child support debt.
The Economic Impact Payments (EIP 2), authorized by the Coronavirus Response and Relief Supplemental Appropriations Act of 2021 are not subject to offset for any reason.
