The fact that it is taking the IRS longer than 21 days to process your return does not mean TurboTax made a mistake. You do not get a refund from TT because it takes the IRS longer than you expected for your federal refund to be issued.

No, a delayed refund doesn't mean there's a mistake on your return. First, check the IRS Where's My Refund? site to get the most updated status of your 2023 refund.
The IRS is taking more than 21 days (and up to 90 to 120 days), to issue refunds for tax returns with the Earned Income Tax Credit and Child Tax Credit.
