After you file

Was the three-way call between you, your bank, and TPG?

 

Does TPG say they received your initial deposit from the IRS at their intermediary bank?

And does TPG say that they then sent it electronically to your bank account after subtracting the TurboTax fees?

 

If so, have you kept checking the TPG refund tool in case the deposit was returned to them (TPG)?

To log in, choose the "For taxpayers" portal.  Then at the next page choose "Check with TPG."

Since electronic deposits use the ACH (Automated Clearing House) system, TPG should be able to have ACH trace the deposit.
