Final answer:
Moving expenses are no longer considered an itemized deduction for most taxpayers, while medical and dental expenses, and some unreimbursed work-related expenses can be itemized if they surpass certain AGI thresholds.
Step-by-step explanation:
The itemized deduction that is not included in the list provided is A. Moving expenses. After the Tax Cuts and Jobs Act of 2017, moving expenses are no longer considered deductible for most taxpayers.
However, B. Medical expenses, C. Nonreimbursed work expenses (under certain conditions for specific jobs), and D. Dental expenses can still be considered itemized deductions if they exceed certain thresholds compared to the taxpayer's adjusted gross income (AGI).
