Hello Shawn E. Although this might answer the question, can you provide some additional explanations? Maybe that would be helpful for others.

Shawn E's answer is probably the correct answer but my wireshark version doesnt have that filter. Following filters do exists, however:
To check if the SNI field exists:
ssl.handshake.extension.type == 0
or
ssl.handshake.extension.type == "server_name"
To check if an extension contains certain domain:
ssl.handshake.extension.data contains "twitter.com"

Newer Wireshark has R-Click context menu with filters.
Find Client Hello with SNI for which you'd like to see more of the related packets.
Drill down to handshake / extension : server_name details and from R-click choose Apply as Filter
.
See attached example caught in version 2.4.4

For a more complete example, here's the command to show SNIs used in new connections:
tshark -p -Tfields -e ssl.handshake.extensions_server_name
-Y 'ssl.handshake.extension.type == "server_name"'
(This is what your ISP can easily see in your traffic.)
