Thank you for the continued help & suggestions! I agree that it didn't sound quite right.
(thanks for sending the prior-year return link as well! That's the process that I've been following.)
The PDF download is a great idea, but unfortunately still seems to only reflect my W2s but none of the additional information I had entered. I'm not sure whether that's because the return was never finished or if it means the data was gone, but either way, it's missing.
