you'll need to start a refund trace. Call the IRS Refund Hotline at 800-829-1954 and use the automated system or speak with an IRS employee.
I had the exact same problem happened to me and with a chime account as well. Apparently The IRS is investigating because money is just disappearing from people's refunds. It's been 9 months and the IRS hasn't even gotten around to my case to trace it because there's so many of these claims of people who worked with TurboTax.
Did you choose to pay your TurboTax fees by having the fees deducted from your federal refund? If so, your problem might be with the third party bank.
When you choose "refund processing" TurboTax gets its fees when the IRS releases your refund. Your refund goes to the third party bank. The bank takes out your fees and then that bank sends the rest of the refund to you.
How can I see my TurboTax fees?
