@Manasahr You should move DocumentBuilder’s cursor to the target paragraph. Once you create DocumentBuilder it’s cursor is at the beginning of the document. I would modify your code like the following:

bool hasToc = doc.Range.Fields.Where(f => f.Type == FieldType.FieldTOC).Any();

if (!hasToc)
{
    string heading = "TABLE OF CONTENTS";

    Paragraph target = doc.GetChildNodes(NodeType.Paragraph, true).Cast<Paragraph>()
        .Where(p => p.ParagraphFormat.StyleIdentifier == StyleIdentifier.Heading1 &&
            p.ToString(SaveFormat.Text).Trim().Equals(heading, StringComparison.InvariantCultureIgnoreCase))
        .FirstOrDefault();

    if (target != null)
    {
        DocumentBuilder builder = new DocumentBuilder(doc);
        builder.MoveTo(target);
        builder.Writeln();
        builder.InsertTableOfContents("\\o \"1-3\" \\h \\z \\u");
    }
}

doc.UpdateFields();

@Manasahr I see Aspose.Words does not include empty heading paragraph with numbering into the TOC.
