If not, then go to this IRS website for information on reduced refunds - https://www.irs.gov/taxtopics/tc203

Are you also receiving a state tax refund? If so, the state refund is sent directly to you based on how you chose to receive the state tax refund, it does not go through the third party processor.

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/
