My client sold a residential real estate (Schedule E) property. 

I entered all the information about the sale in the Asset Entry Worksheet.

It calculated a loss on the sale of about $19,000. Then it says "Part of Form 4797 to which asset gain (loss) carries: PART I" 

On 4797, Part I, all the numbers look right UNTIL line 2g, which shows up as $0.  It should not be 0; it should be (19,000).  What's triggering this? 

I've searched all over for a box I may have checked wrong but I can't find anything. This is not a converted property or a former primary residence or anything. It's just a rental property, bought in 2018 and sold about 14 months later. 

I'm stuck. Thank you!!
