Other users have reported not being able to import from Acorns as well.
I've reported the importing issue to a TurboTax Moderator, who should see it today. Hopefully, they can troubleshoot it soon or have more info.
There is also an error in the small-print instruction on the import log-in screen as well. It says to use the "2018" mailing for the Document ID, which is obviously wrong. I've requested that "typo" be corrected as well.
