I filed my taxes back on April 27th and haven’t received my return yet even though it was accepted. Why is that?

TurboTax receives no information about refunds. Look here.

Your tax return is the form you send to the IRS that shows your income and calculates your tax. The money the IRS sends back to you is your refund. The IRS does not send your return to you. You send your return to the IRS. After they process your return, the IRS sends your refund to you.

What does Where's My Refund? say?

Did you ask to get your federal refund by direct deposit to your bank account, or as a check in the mail?

Did you select the option to have TurboTax fees taken out of your federal refund?
