>They should just give you an itemized breakdown and ask if it's correct.
I'm sorry, but this response comes up every time, and every time the answer is "yes, that's why I said you should be able to just tell them it's correct." It doesn't have to be any more difficult than checking a box.
90% of people are just going to use the standard deduction (no, seriously: in 2019 it was 87.3%[1]), and for most people their filing status will only change a handful of times in their lifetime. It makes no sense to waste everyone else's time for what should be at most 3 or 4 yes-or-no questions.
