Turbotax does not make estimated tax payments or any tax payments for that matter. Either you made the payments twice or you only made them once but entered them twice. If the former you'll get a refund of the excess. If the latter the IRS will correct the estimated tax payments and send you a smaller refund or even a bill if you end up owing.
