If you used the TurboTax online editions the total price was shown to you when you went through the File section of the program in Step 1. Well, before you filed the tax return.
To access your current or prior year online tax returns sign onto the TurboTax website with the User ID you used to create the account - https://myturbotax.intuit.com/
Scroll down to the bottom of the screen and on the section Your tax returns & documents. Click on the Year and Click on View Order Details
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/
