A download has been processing for nearly 36 hours, TV free 12 days of Christmas, tried re-setting the IPAD twice, deleted and stopped on computer, but it is still in my I Tunes downloads, how can I stop and delete it?

12 Days of Christmas app gave a free episode of Sherlock Holmes on the 2nd day, we are now on the 4th day and I am still trying to finish the download from day 2. It is continually processing, and even though I have plugged in to the computer and deleted it off my I tunes account, it is still showing as processing on the I Pad. I have tried re-setting the I Pad three times, once it seemed to disappear, but now it is back again and stuck on about 90% of processing. How can I stop the download, and then delete the episode from the I Pad?
