You can just do the following now:

Old answer:

It's on the Project's wiki, quoted below.

Via ResolveUsernameRequest

An "entity" is used to refer to either an User or a Chat (which includes a Channel). Perhaps the most straightforward way to get these is by resolving their username:

from telethon.tl.functions.contacts import ResolveUsernameRequest

result = client.invoke(ResolveUsernameRequest('username'))
found_chats = result.chats
found_users = result.users
# result.peer may be a PeerUser, PeerChat or PeerChannel

See Peer for more information about this result.
