Deductions & credits

Hi I have been trying to find how to enter a total of my losses not covered by insurance without having to itemize each one but am still unclear where that can be done.  I see that the amount can be added to the standard deduction but other than the form 4684 I do not see where, and from that form it seems you have to itemize separately.  I can itemize the pool equipment, boat dock repair, screen repair, Yard debris clearance, Soffit repair etc, but the contents we lost over our covered amount of $75,000 would be very complicated to list.  We had a total contents loss of $104,101 and the insurance paid $74,907.  All this including our deductible will be in excess of $70,000.

 

Also should i be able to do this, can it also be reimbursed from previous years return as well?

 

Thank you in advance for any help
