That would depend on what specific type of "financial aid" was refunded to you in March.
If you received scholarship or grant monies that exceeded your spring semester tuition and fees, that money would still need to be subtracted from your fall semester tuition and fees before any expenses would be available as the basis of an educational tax credit.
On the other hand, if your disbursement in March was an excess of student loan funds, then all of your tuition and fees could be used in computing educational tax credits, as tuition and fees paid with borrowed funds are still considered to have been paid by you.
There is a place in the TurboTax EasyStep interview for entering qualifying educational expenses for which you did not receive a Form 1098-T.
