I know theres another discussion on this somewhere, but Im not going to go digging.

Put the correct amount of income on that Sch SE Part III Line 18.

Then theres an area on the 1040./1040SR Worksheet that you can get rid of the deferral option.

Scroll way way down the 1040/1040SR worksheet to a box titled Deferral for Certain Sch H or SE filers Smart Worksheet, Line 11 of that smart worksheet, enter zero.   Tada!   No more deferral.
