@TaxGuyBill Thanks so much for your reply! Yes, I can either start from depreciation screen and the sale is reported on form 4797, or I can start from capital gain screen and the result goes to Schedule D. The result is the same.

My questions are:

1 - When a rental was converted to primary home, it is reported on Schedule D? When a primary home converted to rental, it is reported on form 4797?

2 - In your software, can you stop depreciation but still keep the depreciation entry in the software? The information is needed when you sell the home, or otherwise you may need to go back many years to look for the information. 

3 - In a earlier post, https://proconnect.intuit.com/community/proconnect-tax-discussions/discussion/rental-property-sale-w... , we said we should report the land and building separately, how do I allocate Sec 121 exclusion between land and building?
