refund status

[Pat720]

I submitted tax On Feb 2nd.  IRS said they received Feb 6th.  I've called a few times and looked on line to check your refund and no movement.  They are holding our refund and I'm not getting any answers why.  Last time I called they said they would submit a referral and they see their holding with no explaination of why and they could see no notice has been sent to us.

Any ideas how I can get them to let me know reason for hold up?  Thank you

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?
