I sold rental property in December 2021 after not having claimed depreciation for tax years 2012 through 2020 out of pure ignorance as I'm not a real estate professional. Turbo Tax never found errors, so I never questioned it. I now will need to file Form 3115 for sec 481 adjustment as advised by a number of experts here. I'll need to file an extension as I cannot do this myself and use Turobtax Live to work with a professional.
For me to file the extension, I need to pay what I'll probably owe. Using the TurboTax desktop application, what is the best way to get a good estimate with my circumstances? Should I just go through the whole thing without using the 3115 and use that number, or is there a way to get an idea of how to get a good estimate of how much the adjustment might be?
