Refund Delay

[gak3511]

I filed my return in early March and as of this morning, my refund has not been approved.  When I went to the IRS site, they were claiming that they were sending me a form to verify my identity.  I have never received that form nor any other communication from the IRS.  What should I do next?

Here is an FAQ about handling identity verification requests from the IRS.

If you have not received a letter yet, you will be.

Once your return is filed, TurboTax has no control over the processing of your return or the release of your refund.

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"?

Why do some refunds take longer than others?

What if my IRS refund is taking longer than 21 days?
