So since I recently archived the transaction I knew some of the info. On the activity page I searched for the first name associated with it and it appeared in my search resuts. From there, under the heading "Actions" on the results page, I clicked remove from archive for that specific transaction. I'm assuming as long as you can search info related to the instance your looking for (first name, last name, email address, etc.), you can remove the transaction from archive after searching for it. That's all I got for now.
