    @Andriesvc , Welcome to Microsoft Q&A, you could try to convert your textbox's text to a string array.

    Then you could use string. Replace method to remove the line.

    Here is a code example you could refer to.

     private void button1_Click(object sender, EventArgs e)  
            {  
                string[] arr = textBox1.Text.Split('\r');  
                foreach (var item in arr)  
                {  
                    if(item.Contains("baby"))  
                    {  
                        textBox1.Text = textBox1.Text.Replace(item, "");  
                    }  
                }  
            }  
    

    Result:
