I don't understand what you mean by:
"I have to subtract income from my self-employment income because of community property I had to award my ex from our divorce."
Was your ex was awarded an ownership interest in your business? If so, the business would have two owners and would be a partnership, not a sole proprietorship.
If married taxpayers in a community property state file married joint, the self-employment tax is paid by the spouse who earned it and 50% of the community net income is reported as a negative amount on Form 1040, Schedule 1, Line z as, for example, "Spouse's Community Interest in Schedule C Net Income."
