False. The 1040X does not become your new tax return. It lists the changes between your old and new tax return. https://www.irs.gov/faqs/irs-procedures/amended-returns-form-1040x/amended-returns-form-1040x
The IRS states, "Include copies of any forms and/or schedules that you're changing or didn't include with your original return." If you look at the words next to your newly created 1040, you'll notice the word "form", i.e., "form 1040". The whole purpose for submitting a 1040X is because you changed your form 1040.
In short, include your newly prepared return with the 1040X.
