Client had beach condo used as seasonal rental property during the summer months as well as personal use during year 2019.Rental income has been reported on Schedule E for several previous years. In 2019 , client condo burned down completely and received $17,000 for contents inside unit (personal property) from the insurance company. Client was paid $ 100,000 in year 2020 for the actual loss of the unit. Is this a reportable event and what tax form if any is used?

Are they rebuilding or selling the lot and walking away? Look into Involuntary conversion Sec 1033, they can defer the gain for 2 years while they decide what to do with it.

Im not fluent in this type of situation at all, but thats at least a starting point.

It would be nice if you could settle on what software you use.
