How do I fix miscalculation of self-employed health insurance deduction on Schedule 1?

Turbotax has miscalculated the self-employed health insurance deduction on Schedule 1. I'd like to know if there is a fix for this. There are two parts to our deduction. One amount is $1546 and reported on Schedule C, Line 15, off to the side, so not included in total business expenses. This amount is for premiums paid under medicare. The second amount is for premiums for ACA insurance (for husband until he went on medicare and for wife for entire year). Turbotax figures these at $1732 (based on Form 8962). But the total amount shown on Schedule 1 Line 17 is $2606, not $3278 (1732+1546). Turbotax shows the missing $672 as a health insurance expense (however, all ACA premiums for husband and wife should be deductible as self-employed health insurance expense). I encountered this error when I increased home office expenses by about $40. Before I did this, Turbotax was showing correct health insurance deduction on Schedule 1 with no amounts shuttled to health expenses. Of course, one solution is to slightly under report business expenses (go back to the initial figures I used). But is there a fix for this? Thank you. 

 

P.S. I am also using this calculator to check on ACA deduction--it is helpful:  https://thefinancebuff.com/self-employed-aca-subsidy-calculator
