The IRS/state send you a letter a few weeks after they offset a refund for back taxes that you owe.

NOTE: You can contact the IRS Treasury Offset Program Call Center at 1-800-304-3107 to ask if they have an offset for you on file. TurboTax would not have that information.

TurboTax does not receive feedback from the IRS regarding money that was offset from your refund. If you owed back taxes or child support, you will receive a letter of explanation from the IRS in several weeks. The WMR site will contain a message regarding your offset. It is also possible that the IRS caught a mistake you made and reduced your refund.
