Error while trying to read a file with a multi-line textbox.

C#

So I have 20+ richtextboxes and they are all meant to have multiple lines typed into them. But when I try to load this file it puts each line into a separate richtextbox instead of the one they were all typed into. How do I get around this and only have what is typed into a specific richtextbox be opened in that specific box?

Below is my open code. I can post my save code if anyone needs to see it. Please not I've temporarily removed the checkboxes from opening/saving because I kept getting an error during testing for not being a valid boolean. I removed the textboxes and comboboxes from the code below because it said the post was too long.

What I have tried:

        private void OpenToolStripMenuItem_Click_1(object sender, EventArgs e)
        {
            ofd.Filter = "WAP Files (.wap)|*.wap";
            ofd.Title = "Open File";
            
            if (ofd.ShowDialog() == DialogResult.OK)
            {
                StreamReader read = new StreamReader(File.OpenRead(ofd.FileName));

                //replacefridge_ckbox.Checked = Convert.ToBoolean(read.ReadLine());
                //vhoodcab_ckbox.Checked = Convert.ToBoolean(read.ReadLine());
                //vhoodnocab_ckbox.Checked = Convert.ToBoolean(read.ReadLine());
                //furdown_ckbox.Checked = Convert.ToBoolean(read.ReadLine());

                //exhaust2_ckbox.Checked = Convert.ToBoolean(read.ReadLine());
                //exhaustkit2_ckbox.Checked = Convert.ToBoolean(read.ReadLine());
                //timer2_ckbox.Checked = Convert.ToBoolean(read.ReadLine());
