Turbo tax is miscalculating how my Self-employed health insurance deduction after calculating the premium tax credit? How can I fix this?

Self employed and purchased health insurance for my family through the ACA. I received a health care premium credit for some of this  and thought I should be able to put the balance as the Self-employed health insurance deduction. Turbo tax supposedly calculates the amounts - but it there is only about $3000 in the Self-employed health insurance deduction in in Schedule 1 line 16 when the amount I paid after the premium credit is over $5000.
