Thank you JD and C3. But my concerns are as follows: 1. Schedule C top line is sum of all 1099 Misc (we get about 5-10). Twice now (2017, 2019) IRS claimed we didn't report one of them, and I had to send them calculations as to how they add up and flow through to Schedule C. 2. We submit all kids' college expenses to 529 plan and they reimburse and report to IRS as eligible expense. Then why does IRS say we never reported that either? As I stated earlier, since it is electronic filing, IRS computer data should match Turbo Tax data without having to send them paper copies of forms with explanations? It is a hassle dealing with this since it takes months before the matter is closed. Hence my concern - is there a glitch between Turbo Tax and IRS systems? And, should I hire a CPA starting 2021 (have always used Turbo Tax, but seldom had IRS question returns)? Or, does Turbo Tax provide a service for a fee that will take over these hassles and resolve them? PS: Is faxing IRS same as certified mail?
