TMA attachments from file name

I have a number of files that have been uploaded via TMA to send the Statutory undertakers. The undertaker has responded saying they can’t access certain files. After investigating, the files have no size. There must have been an error uploading them.

Is there a way to see from the attachment URL which notice is linked?

I have looked in “Document” (DOC0100) as I would if this was a PEM or Asset attachment. None of the TMA attachments are registered here. I could look at all sent items in Monitor web services but without going into each one I would not know which have attachments.
