How do I report the sale of a former rental property?

See this TurboTax support FAQ for the sale of a rental property - https://ttlc.intuit.com/turbotax-support/en-us/help-article/real-property/sold-rental-property-report/L4No7YsIW_US_en_US?uid=m72ekw0t

It depends.  If the rental is still part of your tax return I will provide steps or if it is no longer part of your tax return. Likewise you will see how to arrive at your sales price(s) and sales expenses.  

First the selling price: The selling price should be prorated for each asset then entered for each asset when you indicate they were sold or disposed of. You will not lose the remaining depreciation because you will use the remaining basis against the selling price to determine gain or loss. 

To figure out the selling price for each asset:

1. Take the current basis of each asset against the total combined basis of all of your assets to figure out the sales price for each one; OR 
2. Determine a fair market value for each asset against the total value of all assets to figure out the sale price for each one. 

Use the original cost of each asset listed on depreciation, add those together then divide each one by the combined total to find the percentage of the cost for each asset.  Use that percentage times the sales price and sales expenses to find the selling price/sales expenses for each asset. (Choices would also be fair market value on the date of the sale or adjusted basis on the date of the sale, which is cost less depreciation.)

Example:  Original Cost (of each asset on your depreciation schedule)

$10,000 Land                = 13.33% 

$50,000 House              = 66.67%

$15,000 Improvements  = 20%

$75,000 Total                 = 100%

Multiply each percentage times the sales price/sales expenses to arrive at each individual sales price/sales expense.
