After you file

The IRS sent your stimulus payment to the account where your last refund was paid.  If you used TurboTax and paid with your refund, then that refund went to the Santa Barbara Tax Products Group.  

 

The Santa Barbara Tax Products Group takes out the money that you owe to TurboTax and sends the rest to you.

 

So the account on record is the SBTPG.  They got all the stimulus money and sent it back to the IRS.  The IRS will issue and mail a paper check.
