How can I integrate Jotform with Salesforce without creating duplicate?

How can I integrate Jot form with salesforce without Creating duplicate Accounts. Ex. When i create the contact Alfredo Ford salesforce create the account Ford Household and if i create the contact Carmen Ford salesforce create another Ford Household instead add the contact Carmen Ford to the existent Ford Household

Greetings!

I do not think that you can add additional info to the existing contact in Salesforce. However, do note that you are given an option to update your record in Salesforce if an existing record is found. Check the screenshot below.

 If, in any case, I have misunderstood your concern, please do not hesitate to let us know and give us more details about your requirements.

Thank you.

Good Morning Ms. Cecile,

Thanks for your response. I Added that checkmark, and it was worse because the system didn't add the contact in Salesforce.
