Once a tax return has been Accepted by the IRS or a State, TurboTax receives no further information concerning the tax return or the status of any tax refund. Only the taxpayer listed on the tax return can obtain the status of a tax refund or a tax return.
You should be receiving a letter in the mail from the state which will explain what they changed on your state tax return to reduce the state tax refund. There may also be a procedure to use in the letter if you disagree with the state's explanation.
