Tell us what’s happening:

I don’t know where to insert this in the code: event.preventDefault()

Your code so far


class MyForm extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      input: '',
      submit: ''
    };
    this.handleChange = this.handleChange.bind(this);
    this.handleSubmit = this.handleSubmit.bind(this);
  }
  handleChange(event) {
    this.setState({
      input: event.target.value
    });
  }
  handleSubmit(event) {
    // change code below this line
this.setState({submit: this.state.input})
    // change code above this line
  }
  render() {
    return (
      <div>
        <form onSubmit={this.handleSubmit}>
          { /* change code below this line */ }
<input type ="text" value = {this.state.input} onChange ={this.handleChange} />
          { /* change code above this line */ }
          <button type='submit'>Submit!</button>
        </form>
        { /* change code below this line */ }
        <h1>{this.state.submit}</h1>
        { /* change code above this line */ }
      </div>
    );
  }
};

It probably should go here because you are preventing default action of a submit button to go to other page.
