Thunderbird and multple email accounts

this question is from an unsophisticated p.c. user. my problem is that i use the Thunderbird email program, and maybe because i changed the settings (i don’t know), Thunderbird collects email from another email account that i don’t want it to. how can i turn this function off? i can’t seem to find anything in the settings to help. thanks.

Try under
Tools/Account settings.
You should have a list of accounts there.
