Ah, I take it that you are sending in a paper return. When I used to send in paper returns, I would staple the W2s to the 1040 in the section where required.
Also, you are allowed to staple the pages together, just don't staple the 1040 in the upper right corner of the form.
Please let me know if I can be of further assistance to you regarding this matter.
Yes, that is correct.
