$4,800 in health insurance premiums paid - and $0 APTC. Linking 1095-A to Sch. C stunts the deduction down to $1,500. I want to see the iterative formula, but ProSeries does not show it. Can I not link the Form 1095-A to the Schedule C, and instead make a direct entry into Line A1 of the SE Health & LT Care Dedn Wks?  There is high enough profit to accommodate both tax payer's SEP IRA contribution and the the full SE health insurance deduction... I think that the ProSeries iterative formula is somehow looking for an APTC that is not present. Have performed manual calculations in worksheets from Pub 974 & Pub 560... should be allowed full SE Health Insurance deduction from what I calculate.
