Have not taken rental condo depreciation ever
I realize now I should have been taking rental condo depreciation and I never have.
The condo started being a rental in November 2015. I have filed for an extension for the 2020 taxes as I realized this.
Suggestions on what I have to do to fix it? I think I have to file form 3115 with 2020 taxes, application for change in accounting method. Can I do this with TurboTax? Do I have to file amendments for previous years?
Thanks for any help you can provide!
