How do you properly depreciate solar panels if you have a home office? Turbo tax automatically assigns a 39 year recovery period but per Pub 946 it should be 5 years.

The home office solar panel depreciation appears automatically as a 39 year property on part III line 19i on form 4562. Based on Pub 946 I would expect to see it on line 19b as a 5 year property with a higher depreciation deduction.
