This is quite common. Your return is probably 100% correct but the IRS can do "reviews" or "audits" any time they want. TurboTax has no control over what the IRS does.
The IRS has several different methods for a review:
- Random selection and computer screening - sometimes returns are selected based solely on a statistical formula. The IRS compares your tax return against “norms” for similar returns. The IRS develops these “norms” from audits of a statistically valid random sample of returns, as part of the National Research Program the IRS conducts. The IRS uses this program to update return selection information.
- Related examinations – The IRS may select your returns when they involve issues or transactions with other taxpayers, such as business partners or investors, whose returns were selected for audit.
