I do not and have never had a farm. Why do I always get a form asking about farm income and expenses?

You need to delete Schedule F and any related schedules or worksheets: 

1. Open your return in TurboTax. (To do this, sign in to TurboTax, and select the Take me to my return button.)
2. In the left side bar, select Tax Tools> Tools.
3. In the pop-up window Tool Center, choose Delete a form.
4. Select Delete next to the form/schedule/worksheet and follow the onscreen instructions.

OMGoodness - what the heck, Intuit!  Farm Farm Farm - I DON'T HAVE ONE!.

Why are you stuck on FARM INCOME.  Desktop software tells me I indicated that I have FARM Income.  When I try to delete, it takes me to my Business Income.  And trust me, I not FARMING!!!  There is NO SCH F to DELETE.  Huge flaw in DESKTOP TURBOTAX BUSINESS!!!  

What if there is no schedule F to delete, which other form that would cause this form to generate? 

If you are using Turbo Tax Home and business software, go to:

1. Business>farm income and expenses>farm income and expenses
2. Navigate to a summary page, if one exists
3. If one exists and if anything is listed, delete it.
