This is not an acceptable answer. The reason for doing the import is to avoid doing manual entries, which can be very tedious. The import facility works with custodians other than TD Ameritrade (e.g. Schwab), it works for some TD Ameritrade accounts, but not all. and has worked in previous yeras. The account I cannot download has the same Account Number and Document ID as last year, and it worked then.
The problem appears to be on the TurboTax end, not at TD Ameritrade. The error messagwe comes up immediately before it even attempts to log into TD Ameritrade. I noticed that on documents that do download successfully they contain alpjha-numeric Doc IDs. The one that fails is all numeric.
I hope this helps, and I really hope this gets resolved.
