Refund still not arrived, got a notice that they did a manual review

If your return is under review your refund will be delayed.

MY RETURN IS UNDER REVIEW

The IRS is getting more and more vigilant to prevent identity theft and fraud.   People who file very early in the season are sometimes scrutinized more.  Do not take it personally.   TurboTax does not get any information from the IRS after they accept your return, so no one at TT knows that your refund is delayed or why.  All you can do is wait for the IRS to finish processing your return.  Watch the refund site.  If the IRS wants more information from you they will request it. If they want you to verify your identity, you must follow the IRS’s instructions in order to do that.   In many cases they will send you a letter—and you will have to wait for that letter.

A manual review, human inspection rather than automated processing. 

• It may be because of errors, inconsistencies, or identity verification concerns. 
• It may delay your refund for 45 to 180 days or longer.
