@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:
