After you file

The exact same thing happened to me! I filed on 1/26, accepted on 1/27, WMR had one bar saying received, on 2/12 I changed to PATH ACT message and then on 2/15 WMR changed to no bars and says your return has been received and is being processed with no tax topics. I called the IRS on friday and was told that my refund is on due to a review of my income and deductions/credits. She said a letter was mailed out to me on 2/20 advising me of the review and that I need to allow 45 days  to be complete but not to call back until after 60 days if I havent received my deposit or another letter. She said it doesnt show that there is an error with my income or credits but they have to review it to make sure everything is correct and if something isnt correct then they will send another letter and I will have to wait another 60  days. I have NEVER had anything like this happen and cant seem to get any answers. Please update if you get any information!
