The big thing is that a long time ago that sort of itemized deduction stuff mattered a ton, now, almost everyone just takes the standard deduction. Your tax preparer was just going "hey, is there anything special that makes it worth itemizing?" and the answer was no so they went standard deduction. Like, 90% of people are better off standard deduction now, you need a really specific business type situation to get anything from itemizing and will just work it all out, see the number is lower than the standard deduction and take that instead.
