Code 570 doesn't mean audit. It typically means there a hold on your return due to money you owe to a government agency or something, ie.... back child support, defaulted student loan, unpaid state taxes, etc. I had a friend have that code last year from her student loan being in default. They applied her entire refund to her student loan debt. My exhusband lost his entire refund for two years to pay towards catching up on his child support.
