Retirement tax questions

Hi, I'm still stuck on this, and could really use some advice.

I've answered the questions on line D1 and D2 on the Qualified Business Income Deduction Smart Worksheet.  No matter what value I enter into line E5a I get the "Check This Entry" message.  I've tried entering $0, which is what the program shows for "Self-Employed Health Insurance" Deduction (see attached).  I've tried entering $3697, which is the amount I actually paid for my health insurance.  I've tried entering $4824, which is my share of the  Health Insurance Premium Tax Credit my wife and I received.

Can I just ignore this error?  After all , the worksheet states: "Completing this worksheet is generally only necessary if Form 8995A must be filed (i.e., taxable income is above threshold amounts . . ." 

My taxable income is not above threshold amounts, and Form 8995A is not being filed (it is not in the list of forms).

Any help would be greatly appreciated.  Thanks.
