No, only the newly corrected Form 1040 and 140 should be mailed with the Form 1040X and 140X. Generally, you should wait until the original return has been processed (refund received or payment deducted from your bank account) before you file the amended tax return. Because of COVID issues, the IRS has currently suspended processing paper returns of any kind.
The Form 1099-MISC you received should be entered into TurboTax for your amended tax return. You do not have to attach the actual 1099-MISC form when you mail the Form 1040X but Arizona does require the Form 1099-MISC to be attached after the last page of the Form 140.
