After you file

If you paid the TT fees yourself with a credit card then you didn't use the Refund processing service so ... if the IRS says sent the refund then either they  took it back ( it happens sometimes) or your bank refused the refund and sent it back ....  now  it will take the IRS 2 weeks or more to convert the refund to a paper check mailed to the address on your return.  But  at no time is TT in this mix and cannot help you locate the money.
