If your name was not on the bank account then the tax refund could not be direct deposited into the account. The refund would have been returned to the IRS and they would have mailed tax refund as a check to the address on the tax return.
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.
