How do I enter repayments to the VA for GI bill overpayment in turbotax?

Last fall I had to withdraw from courses funded by the Ch 33 GI bill.  My 1098 T still shows the full amount the VA paid to the school, but the VA sent me a bill for most of the money they paid to me and the school.  My 1098 T shows approx $4,000 in expenses, $10,000 paid (between GI bill and Pell grants), but the VA recouped $8,000 from me.  Shouldn't I be able to deduct the net $2,000 I paid?  How do I do this?
