Thank you for the response VolvoGirl. I do have enough profit from my business to allow the SE health insurance deduction. In fact, right after I posted this I discovered the problem. I went to Schedule C, Health and Long Term Care Deduction Work Sheet, and found under B that it showed a $45,000 401K contribution amount. This amount erased my SE income in TT and prevented the SE health insurance from being applied. This $45,000 401K contribution was apparently a left over from when I had been earlier doing some "what if" analysis using the program. Once I zeroed this out, since I do no plan to make a 401K contribution this year, the correct amount of SE health insurance appeared on Line 17 of Schedule 1. Problem solved. I would note that the 401K contribution should have gone away when I reduced my SE retirement contribution to zero under Less Common Business Situations, but for some reason it did not.
