Should adding a depreciation expense increase taxes?

I own a profitable 3-family rental, and in 2021 I did a major renovation ($20k).  So I was playing around with TurboTax 2021 to see the difference in long term depreciation vs. one-time deduction if it qualified.  The odd thing was that my owed taxed increased (the realtime update TurboTax does at the top of the page) when I added a new depreciation line item of $20k.   

 

Do I have some error somewhere in TT that would cause that, or is that expected?
