Do you know what TPG Product Co is? Some say it is federal tax return, but my amount is less than it should be even after my fees to you are taken out?

Is the amount sent/issued by the IRS the same as the refund amount shown on your federal tax return Form 1040 Line 35a? - https://www.irs.gov/refunds

Have you factored in the TurboTax account fees and the TPG service charge of $39?

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 service charge deducted. The third party processor will deduct the TurboTax fees plus the 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/
