The issue is with the state, not with Turbotax. Many states are slow to update their records, and some do not do so until they actually process your filing. After all, it was Mississippi that told TT your return was Accepted for processing. Please see the below statement from the Mississippi Department of Revenue:
Due to the increase in fraudulent activity, the Mississippi Department of Revenue has implemented additional procedures and safeguards into our return processes in an effort to mitigate potential fraud. These processes will validate income tax returns and credits reported prior to issuing requested refunds. As a result, these additional procedures may cause a delay in refund processing in order to ensure that the right refunds are being paid to the right taxpayers.
