I am trying to get Tax deduction because of Coronavirus for my self employed income, it is asking me for my SE form from 2019. but I do not have that form

You do not have to use your 2019 amounts- for some people, it is to their advantage.  Just continue through and you can complete the return.

In late December, Congress passed a law that allows you to use your total net self-employed income from 2019 to qualify for the family leave credit. The credit is based on how much income you earned, so if you had more income in 2019, you'll likely get a bigger credit.
 

Thank you so much.
