Somehow the farm optional method was used on my tax form. How do I remove this? I don't have a farm.

Go back to the Underpayment Penalties and Revisit the section.  

Thanks for your response.  My underpayment penalties hadn't been started, and after i went through and declined them this was the result.

That is pre-filled by TurboTax but is not filed because the amount is 2/3 of gross farm income, but if you did not have farm income, it will not be used.  @dotsonbryan 

Ok.  So I am good to proceed as-is?  Seems odd to have anything in there at all.  Thanks again @MaryK4 !

Yes, you are good to go! It was not TurboTax- it is actually prefilled on the IRS form.  See Schedule SE (Form 1040)
