I got the same notice Saturday 4464c letter basically telling me im under review for my wages. I knew that because my w2 withholding is incorrect on my return just waiting on them to adjust it or give me my money so I can Amend. I have a TA thats how i knew what's wrong with it. You may want to get one because IRS won't tell you whats wrong if anything is wrong. They also will helo speed up your review and u will get your money faster
