How do you know if turbo tax has received their fees from return?

If you requested to have the TurboTax account fees deducted from your federal tax refund, the IRS will send the refund to a third party processor to have the fees and the $40 service charge deducted. The third party processor will deduct the TurboTax fees plus the $40 service charge and then attempt to direct deposit the remaining refund balance into the account that you entered on your tax return.

For the status of your tax refund you will need to contact the third party processor, Santa Barbara Tax Product Group, using their website - https://www.sbtpg.com/

In addition to what is mentioned above, you can log in to your TurboTax account.  Once you reach the landing page, scroll to the right-hand side of the page and go to Turbo Tax Order Details. Select that and it will show as Payment Complete.  Here's a screenshot of the section I am referring to.
