Self-Employed Health Insurance Deduction Worksheet - 2020

At the bottom of the Self-Employed Health Insurance Deduction Worksheet there is a comment

 

"A self-employed health insurance adjustment of $XXXX.XX from premiums paid through an
exchange is included as an adjustment to income but does not appear on these worksheets".

 

The $XXXX.XX is added to the amount on line 10 of the worksheet and transferred to Form 1040 Schedule 1 line 16.  Whats going on here with the "adjustment".  Is this correct?
