I only do maybe one rental sale a season, so Im not fluent on which line should have what, but I just looked at one of my clients that we did a "what if" situation for him to sell a rental.

The 4797 Page 2 should break down the sale for you and the amount on Line 24 should move over to Page 1, Part 1 Line 6, Part 1 line 2 is empty.
