I agree with @KrisD15 , Employer Tuition Reimbursement does not count as scholarship for the 529 penalty exception.
I also agree that since $9,750 of the reimbursement was included in your taxable income, it's not really reimbursement for the purpose of the tax rules. Only the first $5250 is TAX FREE reimbursement.
So, you can take out $9750 from your 529 plan, not only penalty free, but tax free too (no tax on the earnings). And as KrisD15 said, you can take out room and board (with some limits), if you are a half time or more student
