Where's my Refund is the most accurate information as it is directly from the IRS. Once your return is filed, TurboTax has no control over the processing of your return or the release of your refund.
The IRS is who is issuing your refund, not TurboTax, so the IRS has the most up to date information.
Here are a couple FAQs to track your refund:
When will I get my federal tax refund?
How do I track my state refund?
Why does Where's My Refund say "approved" but TurboTax still says "accepted"?
Now status has changed on TT site from pending to Refund but no deposit. Also says REFUND on 02/19. Have NO idea what is going on
