People want simplified tax codes only in principle. Everyone has a deduction or credit they will fight to defend.

I’m not entirely sure what your point is. You say you don’t care about this but seem very invested in defending Intuit’s lobbying.

You also seem to be simultaneously claiming that the US tax system is too complex for the government to feasibly automate and that filing taxes is trivial.

Either you hold contradictory viewpoints here or you have some undisclosed interest in this area.
