Did you select to have the Turbo Tax fees deducted from your refund? Then it goes through a 3rd party bank to take the fees out.
How to contact Turbo Tax

if you chose to have your TurboTax fees deducted from your federal refund then the banking information on the tax form is the information to send your refund to the third party bank. That bank gets your refund first from the IRS. They take out your TurboTax fees and send the rest to you---and that bank has YOUR direct deposit information.
When you choose "refund processing" your refund goes from the IRS to the third party bank. The third party bank takes out your TurboTax fees, takes out its $40 refund processing fee ($45 in CA) and sends the rest of the federal refund to your account. The third party bank does not handle your state refund at all. The state refund is sent to you separately by your state.
If your refund --- minus all the fees--- is less than you expected----first you need to determine if the IRS reduced your refund for back taxes, child support, spousal support, etc. because when the IRS reduces your refund it takes them a few weeks to send you the letter that explains why your refund was reduced
