If I **bleep**. 

I started out saying "If I b i l l e d my clients for the work I put in on a situation like this last night, they couldn't afford me."  Then I explained the situation.  But I'm done with answering questions when my work gets deleted.

I kept making manual corrections, as you say, adjusting the amount shown on the Schedule C entry line.  But whenever the AGI changed, the premium tax credit would change, and I would have to rinse and repeat. 

I'm not sure this is something that software should be expected to deal with.  But I wish this discussion had been posted last week.
