Use parameters. Put ? for every parameter value. Use same order when adding parameter values.

string sql = "UPDATE NewInvoice_1 SET Terms =?, [InvoiceDate]=?, OurQuote=? ... WHERE InvoiceId=?";

            using (var command = conn.CreateCommand())
            {
                command.CommandText = sql;
                command.Parameters.Add(CBL_Terms.EditValue.ToString());
                command.Parameters.Add(CBL_Date.DateTime);
                command.Parameters.Add(TXE_OurQuote.Text);

                //add all other fields keeping order

                command.ExecuteNonQuery();
            }

Side note - you shouldn't really execute or keep queries in a form. Also, if you use adapter, you could use below syntax to add parameters:

command.Parameters.Add(adapter.Parameter(value));
