Rental Depreciation

Hello,

 

I converted my primary residence as rental property in 2017. I have used turbotax to file taxes but have not depreciated rental property. It looks like IRS would assume I have done the depreciation anyway. So have a few questions.

 

1. Can I take the depreciation starting from this year?

2. I should use the fair market value at the time the property was converted to rental (Zillow estimate?) as I had used it as primary residence earlier?

3. Can I include prior years depreciation in this years taxes?

4. Should I file an amendment for last years taxes to take the depreciation? If so, what is the process?

5. Turbotax is suggesting amount of depreciation taken in prior years? Should I use that amount or update it to 0?

 

Thanks
