TurboTax says my refund has been accepted, but the IRS website says it’s still pending. Which is true ?

The IRS refund site does not use the word "pending" so not sure what you are referring to.

FROM THE IRS WHERE’S MY REFUND SITE:

How it works

Where's My Refund shows your refund status:

• Return Received – We received your return and are processing it.
• Refund Approved – We approved your refund and are preparing to issue it by the date shown.
• Refund Sent – We sent the refund to your bank or to you in the mail. It may take 5 days for it to show in your bank account or several weeks for your check to arrive in the mail.

Accepted only means the IRS Accepted your tax return for processing.  The IRS verified your name and ssn.  Then they process it.  Then they Approve it and send  the refund.
