An override can cause the automatic calculations in TurboTax to break in unexpected ways, even in places that you might think are unrelated to the override. Also, an override prevents e-filing and cancels the accurate calculations guarantee. You shouldn't need an override. You might want to post a new question specifically about the farmland rental appearing on two schedules and see if someone can help you straighten it out, or call TurboTax support for help. You might simply have answered a question incorrectly in the Step-by-Step interview, but this is an area that I'm not familiar with.
If you do post another question, please be sure to correctly indicate what product you are using. When you posted this question you indicated that you are using TurboTax Online Free Edition. (See the product indicator to the right of your display name at the top of the question.) But that is obviously not true, since you have forms mode. You will get more reliable answers if you provide accurate information.
