If you are referring to the second stimulus money (2020), then the Second-Round Payments Can't be Garnished
The COVID-Related Tax Relief Act specifically states that second-round stimulus checks are not subject to garnishment by creditors or debt collectors.
The Internal Revenue Service (IRS) says it will not garnish stimulus checks for back taxes. ... It can take your entire stimulus check, up to the amount that you owe. If you're married to someone who owes child support (and you don't), you can file an injured spouse form.
