"If you filed a joint return and you're not responsible for the debt, but you are entitled to a portion of the refund you may request your portion of the refund by filing Form 8379 (PDF), Injured Spouse Allocation. .. Attach Form 8379 to your original Form 1040 (PDF), Form 1040A (PDF), or Form 1040EZ (PDF) or file it by itself after you are notified of an offset."
It doesn't sound like you have a refund coming at the moment. You may have education or other credits.
I trust this clears it up but let me know. Thanks again!
