Feel free to use cross-posting in a way that helps Mastodon grow, i.e. copying posts from Mastodon to Twitter, but please avoid doing it the other way around, see our rules on that matter:

Thank you for understanding!
@Gargron I face this conundrum.
I acknowledge that I am tech challenged. And I see a lot of my posts and RTs from Twitter featuring here. I don't want them to be.
What can I do to stop that? Is there a tutorial or someone who can walk me through as regards what to do?
@majchowdhury Just open up a web browser and type in the url of the instance where you created the account and login! 
Or download any Mastodon application for Android or iOS and login from there with the right instance (server) url where you signed up!
