'reference to partial object in typescript?

I have an object and it's typed

interface formDataType {
  tesla: {
    made: string
  },
  ford: {
    made: string
  }
}
const formData: formDataType = {
    "tesla": {
      "made":"2021"
    },
    "ford": {
      "made": "2022"
    }
  };

then I've a function where its argument is one of [string]:{made: string}, how can I use back formDataType? is there something like objectOf formDataType?
