Assuming you create Form2 as a child of Form1 (from within Form1, do something like Form2 from = new Form2();, you can access any public property of the child form from within the parent. So, just make sure to set the accessibility of the TextBox to public, and do something like this:

var form = new Form2();
form.ShowDialog();
this.TextBox1.Text = form.TextBox1.Text;
