It's possible you may have had a refund offset. You can contact the BFS's TOP call center at 800-304-3107 or TDD 866-297-0517, Monday through Friday 7:30 a.m. to 5 p.m. CST.

TurboTax does not receive feedback from the IRS regarding money that was offset from your refund. If you owed back taxes, child support, student loan debt, etc. you will receive a letter of explanation from the IRS in several weeks. The WMR site will contain a message regarding your offset.

(Be aware also that your Federal refund and state refund do NOT come together)
Did you choose to have TT fees deducted from your Federal refund? (Remember that if you did that, you also agreed to an extra refund processing fee of $39.99)
How can I see my TurboTax fees?
