Hello, I also have this problem. I press autofill my return and I get a page titled "get a jump start on your tax return". I pressed continue like you described and it brings me to a paged that says "great, now lets enter the rest of your tax info!"
To clarify, I've used the download tax info before last year and I even managed to download the info at the beginning of May this year but needed to restart my tax return and I am now unable to download.
