A loss on your farm will be used against other income on your tax return first. So if you have a loss on the farm of $5000 and you have wages of $10,000 then the taxable amount would be reduced to $5000.
If the loss on your farm is big enough to wipe out all of your income and create a negative income for the year then you have what is known as a Net Operating Loss (NOL) and that can be carried forward into the next year. If your income generates an NOL then the TurboTax system will help you to roll it into the next year.
But if your farm loses money you have to use the loss in this year first before you can use it next year.
