I bought my house on 5/1/2014 and the garage in the house is my home office. I always used the depreciation but now I understood that I was doing it wrong. I also know that you can not amend your tax return prior to 3 years. So I wanted to go head and amend the return from 2018 and 2019.
Here is a snapshot of the form 4562 where I want to correct it. I copied it from 2017 tax return. So look where it says 01/2017. Should I place that with the date I purchased the house which is 05/01/2014? Or should it be the first day of the tax return year which in this case is 01/2017?
Also is the row I correct where it says Nonresidential real property? See the snapshot below.
