I have a client who flipped two houses in 2018. This is his business, so the profits are subject to SE tax.  He is a sole proprietor.

I entered the detail on a disposition worksheet tied to his Schedule C. The details flow to Form 4794 Part II as expected.

Form there, the result flows to Schedule 1 line 14. I can't find a way to get them to flow to Schedule C instead.

I can override 4797 line 18 and manually enter the detail on Schedule C, but then I doubt I will pass the e-file blocker stuff.

Am I missing a checkbox or other command somewhere to get this to flow to Schedule C instead of Schedule 1?
