After you file

Because you were reimbursed for this expense by the insurance company, it is not a qualified medical expense.

As the others have said, you shouldn't be using HSA funds (including your HSA debit card) to pay a medical expense for which you know you will be reimbursed by insurance.  HSA custodians are permitted, but not required, to accept a "return of mistaken distribution."  If you know that you will receive reimbursement from the insurance company, it's difficult to establish that the distribution from the HSA was a mistake.  If the custodian is willing to accept a return of mistaken distribution, you'll need to send the money back to the HSA as a return of mistaken distribution so that the custodian treats and reports it as if it had never been distributed.

If the money cannot be returned to the HSA, unless you have previous unreimbursed medical expenses incurred after the establishment of the the HSA to which you can apply the HSA distribution, you'll pay taxes and, if you are under age 65, a 20% penalty on this distribution that was not used for qualified medical expenses.
