Our daughter need to file an amended return for 2023, she must mail in the federal and Arizona returns. Do all the pages of the amended returns have to be sent?

TurboTax will print all pages required and a cover sheet with a list of what documents to include with the amended return and the address to mail it to.  Amended state return will print first and then a copy of the federal return.  Mail everything. Be sure you use the option Print to Mail.  Be sure to sign in the spaces indicated and to use a mailing service that notifies you when the return is received.

My question came about because when I printed the returns, there was no option to 'Print for Mailing'. The printed result contained the amended returns and the original returns (1040 for fed and 140NR for Arizona) which made me question if the original returns were necessary (seemed like a lot of unnecessary paperwork.
