An "accepted" return can still be subjected to further scrutiny by the taxing authority.
It is not at all uncommon for a taxing agency to find errors or omissions on a tax return, even though the return initially appears to be correct when it leaves the taxpayer's hands. What TurboTax guarantees is that its calculations will be correct. But the program of course cannot guarantee that all of a user's entries will be correct.
