As I did a review of my file, Turbotax stated that I needed to enter a value for my business loss/gain. But I didn't lose last year, or gain. So which option do i pick?

It is possible the you entered a K-1 schedule that would report your income or loss from a business that you had an interest in. It may have been carried over from a previous year if you didn't enter anything in the current year. If so you may be able to delete the errant K-1 form, if you are sure you don't need it, by using these menu tabs in TurboTax:

1. Tax tools (on the left menu bar)
2. Tools
3. Delete a form

Find schedule K-1 in the list and delete the form.
