Each state processes differently and at different times, so the time frame can vary. Also, keep in mind some tax returns need extra review for accuracy, completeness and to protect taxpayers from fraud and identity theft. Extra processing time may be necessary.
If you're concerned, please contact your state department of revenue. See the TurboTax FAQ below and click on your state:
