include amended state with amended fed

Hello.

 

I am filing amended returns for 2022 and 2023.  

 

By amending 1040X my state return was also changed.  Do I need to include a copy of the amended state return with my 1040-X?  Do I need to include a copy of my amended 1040-X with the amended state return?

 

I live in Missouri.  

 

Also, according to IRS.gov I should be able to efile the amended 2023 return.  How do I accomplish this using desktop version of TT.

 

Thank you in advance for time and effort to answer my questions.
