Tax Year Prior to 2020: rental house depreciation recapture

[yilliinn]

I sold our two rental house in 2017, and didn't claim the depreciation in the previous years. I know it should recapture when I  sold them, turbo tax asks the amount taken in prior years, do I enter 0? or enter amount I should have taken? thanks.

You file an amended return for 2017 on form 1040X, pay the tax and penalty, then prepare 2018 taxes as normal.

You would enter the amount you should have taken.  I also suggest you file Form 3115: Application for Change in Accounting Method to try to recoup the past depreciation not taken.  Please read more about it at this link.
