Looks like there is a permissions thing when it comes to being able to add comments to IRs (OP shared a screen capture with me, and the only link available to them is "View Set").
My recommendation to all members is to go to the Permissions page (https://www.tcdb.com/Permissions.cfm) and go through the different levels (and actually learn the stuff there - it's not hard), and move yourself up. This way, you can handle a little bit of stuff on your own and be able to do important things, such as comment on your own IRs.
