My status of my return reads under review and I'm trying to see if it's something I did wrong

[CarolynB]

There are a number of reasons why a refund would be place under review.

    Process taking longer than normal (Typical)
    Review for amendment and information (Usual)
    More information is needed (If this is the case it will be clearly stated in the letter or notification)

If the status has changed from "Under review" to "Your return has not yet been processed", it indicates they have completed the review and have sent your return to be processed. They haven't, however, completed the processing.
