I bought a home in 2011, and did some home improvement in 2012 for which I spent about $10000. In 2017 I had to relocate to another state for a new job, and I changed the home into a rental property. Then I sold the home in 2020. Over the years I didn't report the home improvement in tax returns. Now my question is , is it possible for me to add the home improvement expenses back on the 2020 tax returns to increase the basis value of the home , so that I can reduce the capital gain for the sale of the rental property? If this is possible, how can I do it in TurboTax?
Thank you very much.
