For most people, those deductions are less than the "standard" deduction you can take instead. For most of the people who do itemized deductions, it's mostly just your mortgage payment and state taxes, which the IRS already knows about, and maybe charitable donations.

And even if you do have a lot of things to report, why not just report those things directly and let the IRS calculate your taxes, rather than you having to do it, fill out a complicated form, then the IRS does the calculation anyways to make sure you did it right?
