iTunes: You have 1 item awaiting download

If I bring up my Account Settings screen in iTunes*, at the very top, immediately under the Account Settings heading, it says “You have 1 item awaiting download…” Next to that, there is only a “Download Now” button, and below that are two more sentences describing what I might be able to do with said item after downloading.

It does not tell me what the item is, or (far more concerning to me) how large it is. My SSD is only 256 GB, of which I have only 56 GB remaining. This will be the last time I cheap out on the internal storage.

Is there any way I can find out what item this refers to? The strange thing is, I have a lot of iTunes purchases that haven’t been downloaded, yet iTunes thinks it’s critically important to let me know about only one of them.

*Yes, iTunes. I’m still on Mojave.

I don’t understand its logic here.

Thanks,
