I have a new client with residential-rental real estate. I have to re-key all the data from scratch (no electronic data available). The situation is that her husband died in 2018 and in 2019 she sold a residential-rental real estate property. I am having trouble figuring out how to input the information into ProSeries for the stepped up basis and expenses of sale. I calculated what the gain would be manually on paper but my inputs into ProSeries is not returning the same amounts. Can anyone share a step by step guide for how to do this correctly?
