WHY ARE YOU TRYING TO FILE BEFORE THE IRS IS EVEN PROCESSING RETURNS THIS YEAR ???
Please don't be in a rush to file. In the past when there have been major tax law/form changes many of the early filers got caught in a black hole and their returns were delayed for months in processing or were lost altogether and they had to refile. So don't be in a hurry to jump into the deep end early. The IRS has not even posted a start date for processing 2020 returns and it may not start until sometime early February.
That warning said ... look at the form 7202 : https://www.irs.gov/pub/irs-dft/f7202--dft.pdf
This form has a deduction that you can use as a SE person so even if you will not take advantage of it you must still complete that section of the interview and the program is not fully functional in that area. Patience will be needed by all again this year.
Per the IRS instructions for form 7202:
Self-employed individuals should use Form 7202 to figure the
amount to claim for qualified sick and family leave equivalent
credits under the FFCRA on their 2020 tax return. These credits
are available to eligible self-employed individuals if they were
unable to work or telework or had to care for family members for
reasons related to the coronavirus and are refundable.
