1.Click on the "Insert" menu and select "Drawing".
2. In the Drawing window that appears, click on the "Text Box" icon (it looks like a square with a "T" inside).
3. Click and drag on the drawing canvas to create the text box.
4. Type or paste the text you want to appear inside the text box.
5. Use the formatting options in the toolbar to customize the appearance of the text box and its contents.
6. When you're finished, click "Save and Close" to insert the text box into your document.
That's it! You've now added a text box to your Google Docs document.
