TurboTax Business calculated no tax due on a complex trust with Ordinary and Qualified Dividends. IRS has just notified me that they believe tax is due at a 15% rate as per Schedule G. I'm not able to use the Qualified Dividends Tax Worksheet because short and long term gains were reported in Sched. D Parts I & II. That Worksheet would have calculated no tax due. TurboTax found no errors when running reviews and error checks and still says no tax is due. Why?
