There are numerous items, so can i just list them as jewelry, clothing, electronics etc, or do i have to list each item (1 carat diamond ring, 1 Macbook etc??)
You will clump items together - personal property covers your personal items. The IRS has a great workbook for personal items. Publication 584, Casualty, Disaster, and Theft Loss Workbook (Personal-Use Property)
Is there a summary page like in the IRS Pub. 584 workbook where I can list each of the items instead of doing a new form for each item? Because TT asks for a date item is acquired, I don't think we are supposed to "roll up" the items on the IRS Pub. 584 workbook Schedules 1-19 (e.g., Schedule 1 is Entrance Hall). Why doesn't TT have a question like "Is the address the same for each property item?"?
You should add all of your personal items together and enter one disaster loss and call that "personal items". Maintain records of all of the losses in case there is ever any question of the valuation.
