All your reviews are on your user-page see
https://math.stackexchange.com/users/current?tab=activity&sort=reviews
Alternatively you can consult the "history" of the relevant review queue (exists for each queue):
https://math.stackexchange.com/review/suggested-edits/history
There is a switch to see "all items" or "only your items" (the former is not available to all users, access is a separate privilege).
To see how the review played out in detail, click on the "reject" (not the question title) to get to the review summary that tells you exactly what happened.
