Prepayment available status. Employee inactive

Hi

We have a cheque number by which various expenses and also a prepayment was paid to an employee created as supplier. This prepayment was not adjusted against expenses

This supplier has been inactivated on 31 jul 15

The prepayment was made in june and still shows as available.

As per the business the employee has paid back the prepayment amount.

is there an alternative way to settle the prepayment which still shows as open
