They shouldn't have to fill out the forms at all. For the average person it should be a literal "yes, that looks correct" online check box. That's exactly what TurboTax doesn't want.

Yes, and it's awful. I have ADHD and even with turbotax handholding me and importing last years' data and grabbing some fields automatically, it's still quite stressful.

I know several folks that have their partner do it cause they just hate it.

So the "quite easy" is far from universal.

Maybe in some circumstances. I’ve been dealing with some horrific tax issues. My wife and I have taken off work to fill out forms.
