Tax Year Prior to 2020: Claiming money spent on refurbishing a previously rented condo for sale

I recently sold a condo that I have been renting out for about 18 years. To fix it up prior to selling, I spent about $22,000 on it. I know I can claim for major items like appliances, carpets and so on, but what about all the little stuff like angle stops, masking tape, caulk, paint, mouldings, tile etc?  How can I claim for about $1,000 in incidentals?
