How can I map 'Single Choice' field (which is radio button) to Airtable?

I'm able to map dropbox to single select but seems there's no way to map for radio button which is also a single select to me.

The Single Choice field on your form should be mapped to Single Select field type on Airtable. This field type is the same on Airtable for both the Drop down and Single Choice fields.

Please check the screen cast below where I have mapped both fields to Single Select field on Airtable. After integration and submission, I am able to view the data correctly on Airtable.
