Sale of rental property/Schedule E/Depreciation.

I sold my rental apartment on March 1, 2019. 

For the past 20 years I have been allowed depreciation of $3,672 each year. Do I enter 20 (years) x $3672 for the depreciation figure when reporting the sale of the apartment?

 

Do I enter a depreciation figure for 2019 on Schedule E even though the apartment was sold on March 1st? Can I pro rate depreciation? Schedule E is showing depreciation for 2019 as $3,672 as it does each year.

 

I had no rental income in January and February 2019. Can I  submit a Schedule E? I paid management fees and other taxes in January and February, and so had a loss.
