Right, Intuit or Turbo Tax does not send your check. Unless you are getting a refund for the fees. Did you select to have the fees deducted from your federal refund? Then it goes thought a 3rd party bank (not Intuit) to take the fees out and send you the rest. If they couldn't deposit the rest of it then they will send you a check. So could the check be from SBTPG? Is the check for the right amount of your refund or minus the fees?
