I am not excusing the lack of transparency.

There was a law change regarding kiddie tax this year. In the old days we had to use parents tax rates and simultaneously do the whole family to enter taxable income/capital gain income/etc into each return for parents and each child (method A).  Then rules changed to use the super high trust tax rates instead (method B).  Now for this year we get to choose method A or method B. In other words at least 3 times the work just to properly take care of client. 

I do not know when all of this was finally put into the software. But could the tax change that you found be related to this horrible procedure? [I think that Congress and IRS are also at fault in addition to Intuit]
