Investors & landlords

I did a side-by-side comparison, here is what I found out.

 

Adding a $20k 5yr depreciation improvement to my rental changed the following on my 1040.

 

Line 13 decreased $800 (Qualified business income deduction from Form 8995 or Form 8995-A)

 

on form 8995-A
Line 2 decreased $4000 (I'm assuming is related to the $20k / 5yr) Qualified business income (QBI) from the trade, business, or aggregation.
Line 3 decreased $800
So basically almost every other line on form 8995-A is decreased by $800.

 

Basically the QBI is getting reduced $800 when I add the $20k improvement asset. Is that normal?
