This is exhausting.  Every year for the past decade importing from TurboTax online has been a problem.  IT'S THE SAME COMPANY!.  Figure it out, Intuit.  Jeeze.  From my research, if you happen to have TurboTax desktop, you can open the online file in desktop, then save it again and it should import fine.  I, personally, and not buying a copy of desktop so that I can import TT files.
