Well, there are two things going on here.

Norquist does oppose efforts by the IRS to (partially) obviate TurboTax by having the IRS do your taxes [1].

Separately, he has the anti-tax pledge you mention. The former is not entailed by the latter, at least in any obvious way.

So the parent is right about Norquist opposing filing simplification, but wrong about it being related to the infamous pledge.
