Form 1041 - PR filing Estate Income Tax Return for Deceased

I am the Personal Representative for my Mother's Estate.  She died 2/17/19.   Only assets are home and car.  NO income from bank account, CD's, anything.   

I created EIN to obtain a bank account to put $$ from sale of car/house.  IRS says I need to file Form 1041 by 4/15/2020. (July 15,2020 due to COVID)

 

The house just sold on April 6, 2020 and the car is now FOR SALE.  

Do I need to file form 1041 for 2019? and 2020? or do I just file in 2020 with the income from the house sale and car?  2 beneficiaries to create Schedule K-1s for 2020.
