I'm trying to do my own taxes for 2020 tax year and notice that my tax preparer has been using 25-year property for my residential rental properties since they were put into service. How can I fix this? Could I just calculate the correct depreciation using 27.5-year straight line and enter this in form 4562 line 17 starting this year and then continue until it is fully depreciated in the 27.5 years? Or is this more complicated?
Also, last year I added a new roof to a property that was put in service a couple years ago. Do I add this to line 17 or do I have to put this in line19h?
