In 2015 I rented my home for 365 days. My depreciable basis should have been $120,000. As it was the depreciation expense on my Schedule E was only $1309. In addition, there was no From 4562 filled out by TurboTax for my 2015 return so I'm not really sure what TurboTax used as my depreciable basis. What can I do to get this information?
