Deductions & credits

I started using my garage as home office the day I bought the house which is 05/01/2014

 

This is form 8829   line 39 and 41

Also every year beginning 2014, section III of form 8829 shows values. But the problem is I made a mistake and I typed in 01/01/2015 in 2015 and 01/01/2016 for 2016 and on. I guess it should have been 05/01/2014 for all years because that is when the depreciation started right?
