Import Step: Where would you like to import the entries?
Don't worry: You can change your selection after you make it.
If you want to add entries to an existing form, choose "An Existing Form". You will be able to add new fields to the form.
If you want to update existing entries, choose "An Existing Form".
If you want to import entries into a form that doesn't exist on the site, choose "Create a New Form".
If you are unsure whether a form exists or not, click "An Existing Form". You will see a list of active forms. If the form is not available in that list, you can change your selection later.
