Do I need to declare depreciation in 2020 for my rental house or will it happen automatically based on my form 4562 in tax year 2019.

I see Schedule E (of course) and Form 4562 (Depreciation and Amortization) on my 2019 taxes (completed in 2020) but unsure whether I have to take depreciation again for 2020.  If so, it's unclear to me how to do this.
