You simply cannot report K-1 (1120-S) income as self-employment income. 

Shareholders of an S corporation are not self-employed; they are employees of the corporation if they perform services for the corporation on a regular and continuous basis.

If you did not pay yourself a reasonable salary, you might want to consult, in person, with a tax professional.

hopefully, the S-Corp return was filed by its due date of 9/15/2020. if not you face about a $200 penalty for late filing.
