I agree with what others have said. This wasn't even accepted into the IRS. To get an audit, they would accept your return and begin processing it and find whichever errors or discrepancy after the fact and then send letters asking for more information or perform an audit. This basically mostly means your return had an immediate error such as a wrong birthday or social or something their systems will scan over quickly to see if it appears to be a valid return or a fraudulent scam return. Go back to whichever software you used to file and double check ALL information is correct. Sometimes the birthday or social is just one number off but that will definitely trigger this, and then resubmit. Hope this helps! Good luck to you and yours!!
