I'm Mailing out 2019, 18 and 17 prior years taxes. Do I need to send copies of w2?

I'm mailing out prior years taxes and got them all finish. Do I need to include copies of w2, 1099s, 2095sa and my 1099-B? Not sure why I would have to send copies of my w2s and stuff when they have all that information already. 

 

There are some 1099-Bs I can't get at all because the brokerage firm was taken over by Etrade and they are no longer accessible. Also missing a W2 as well from a previous employer that's not responding back. I plan on using form 4852 for that. I used my wage and income transcripts for all the information I am filing with these returns. 

When I mail these out should I send them certified mail? 

 

 

 

Also I have 1099-Es but only have 2021 and 2022 none for 17.18, or 2019. Do I need to send copies in or can I leave them out?
