Maybe, the solution is to leave the information about the jointly owned property in place. Then simply add another asset as of the date of the death of spouse in the amount of 50 % of the increase in the value of the rental property. Let's assume the stepped-up value increased by $100 K with land increasing in value by $40k and building by $ 60k. The 50% of the increase is $20k in the land value and $ 30k in the value of the building. So, the new asset at $20 k for land and $ 30k for building will be added as of the date of the death of the spouse. This process will avoid retirement of the asset and editing issues within Turbo Tax.
