I have the same problem (2019 corporate FYE 9/30/20).  I correctly checked both of the first two boxes on screen 4.1 and input the bank information properly.  I see the Form 8050 with the correct information, but the letter does not indicate the refund will be direct deposit!  I spoofed the CA estimate paid to force an overpayment....and the letter correctly indicates the direct deposit of the overpayment.  Any help here?
