Investors & landlords

Sorry, I just reread your post and may have misunderstood. I did check line 18 on Schedule E for previous years and zero depreciation was listed for all years. Does that mean I can then write zero for depreciation taken in previous years when I report the sale? Or must I still use what TurboTax says the depreciation should be because the IRS requires depreciation recapture regardless of whether it was claimed on previous returns or not? Does what you were saying about Form 3115 need to be done if I want to then claim the depreciation that my preparer did not claim in the previous years? Regardless, I still need to use the TurboTax depreciation amount for this year even if I fill out Form 3115?
