If you received a notice from the IRS regarding the adjusted refund, it should also list contact information for the agency that received the offset payment.
This article from the IRS says, "It will also include the agency that received the offset payment. It will also give the agency’s contact information."
If there's contact info on the letter you received, I'd recommend contacting the listed entity to inquire about the offset. TurboTax doesn't have access to see any of that information since it comes from the IRS.
