After enabling multiline properties for text boxes, the transfer every 40 characters can be implemented with this code

  for (int i = 1; i < textBox1.Text.Length; i++) if (i%40==0) textBox1.Text = textBox1.Text.Insert(i, Environment.NewLine);

Or simply:

 textBox1.Text = textBox1.Text.Substring(0,80); if (textBox1.Text.Length > 40) textBox1.Text = textBox1.Text.Insert(40, Environment.NewLine);

if you can drop all unnecessary.
