How do I take just part of the self-employed health insurance deduction

My husband and I are largely retired although I have roughly $5000 of self-employment income and we have roughly $100K of taxable income from Traditional to Roth IRA conversions. We have enough self-employed health insurance deductions to zero out my income and that's what Turbotax Deluxe is doing.  Rather than deduct all the expenses, we'd like for there to be some net income to allow a Roth IRA contribution (which we've already made).

 

How do I tell Turbotax that I don't want to deduct all of the self-employed health insurance expenses?

 

Note we've entered the Roth contribution but Turbotax isn't using that information to reduce the deduction or even to flag that there's an inconsistency when it checks the return.
