I filled February 26, went under review March 16, i was put under examination on May 4.. I called the tax advocate number and they transferred me to the department where my tax return was (examination) and they gave me more detailed information. My withholding amount was incorrect (my tax preparer made a mistake) they sent me a letter asking for additional proofs and I’m just waiting for them to review the paperwork I sent. My best advice is to check your transcript online and try to get a hold of the correct department
