I entered everything in TT (Deluxe, desktop edition) including putting my health insurance premiums in the appropriate box under Business expenses. When I completed the return it showed the entire total of $15,720 deducted in Schedule 1 line 16. if so this is what you told TT you paid for health insurance. and thus would show up on schedule 1 line 16
I went through my folder of tax stuff one last time and realized I had received a 1095-A with zero subsidies and a total of $14,981.52 in column A. I knew I needed to complete that part of the tax return. This is what healthcare.gov says you paid for health insurance for 2020. monthly this is $1,248.46. TT would round to $1,248 for 12 months so schedule 1 line 16 would be $14,976. so which is it? did you pay $15,720 or the healthcare amount? note that the healthcare amount is the premiums for 2020 even though it's likely you paid 12/19 in 1/20 and 12/20 in 1/21. did you have other health insurance such as dental insurance, long-term care insurance that wouldn't be included in the healthcare amount but would be deductible as SE health Insurance ?
I would say this is an issue you should be able to resolve without TT help.
