Selling Rental Property on Contract

I'm selling a rental property on contract.  1st year of contract is this year.  Nice down payment and 5.5% interest, with monthly payments.  Balloon in 4 years.  Per TT, in the SOLD section it says don't mark as sold if using installment method.  Only mark SOLD in the final year.  That's 4 years from now.

However, in the asset/Depreciation section, it specifically asks if I'm using the installment method.  It then goes thru several questions.

So, the question is: How/when do I report the sale?
