Medical equip purchased

My spouse recently passed but a lot of specialized medical aides/equip remain & were dropped off at a "no attendant" donation drop site.

My questions to you:

-- The cost of all these was $1,612, (before sales tax, which is 7% in MD) and I worry it will stand out as a red flag to IRS.

-- No, I don't have any receipts. The receiving organization sent a receipt listing the items, stating to go online in order to establish the cost.

-- Do you think I should depreciate this total by 20% since it's no longer brand new?

-- Do you think I should include the 7% sales tax we spent?

 

THANK YOU SO MUCH FOR YOUR HELP.
