I have the code, but it not embedded. just a link.
<iframe src=’https://services.cognitoforms.com/f/gtCo4qyBokGk61usdzl_2g?id=1′ style=’position:relative;width:1px;min-width:100%;*width:100%;’ frameborder=’0′ scrolling=’yes’ seamless=’seamless’ height=’2143′ width=’100%’></iframe>
Because WordPressdotcom is a type of shared environment, there are certain restrictions on what codes can be used here. More information in this Support document: https://en.support.wordpress.com/code/
Does Cognito allow you to create a form on their site and then simply link to it from your WordPressdotcom site?
