Earlier quoted context omitted.
The form that you fill out has a very tearse description of the field, but the actual instructions are in a separate document. For example, form 1040 is here: https://www.irs.gov/pub/irs-pdf/f1040.pdf and the instructions document is here: https://www.irs.gov/pub/irs-pdf/i1040gi.pdf The instructions make it very clear when a field in the form should be used and what should go in it.
Yes, obviously, everyone knows that. When all you have to file is a 1040, reading one of the instructions documents is fine. When you have to use several forms it start to add up.
It's pretty clear that daemonologist did not know that. Which is weird, given that all the tax law the average USian needs to know is "Read and follow the instructions for Form 1040.".
(RIP 1040-EZ. You were a good form.)
Also, I've had to file several forms in the past. It 'adds up', but it's all mechanically following instructions... not anything difficult.
