When i share my form, and users fill it and submit, where i can find the responses???

You can see your submissions on the JotForm page, this guide will help you to view your submissions: How-to-View-Form-Submissions

You also receive an email notification with the submitted data, this guide will help you to find the email recipient address so you know the email where submissions are being sent to: How-to-Find-and-Change-the-Email-Address-Used-for-Notification-Email

Hope this helps.
