After you file

Once the IRS has accepted your return for processing then and only then will the bank make a final determination on the advance being released.  Turbotax has nothing to do with it once you have submitted your return.  There was no guarantee that the bank would approve the loan even if you were pre-approved in the program.  You must contact the processing bank to see where you are in the system ... no one on this public forum or TT can assist you.
