I have a similar issue, but in reverse. I have created a connected account within Quicken for my 401(k). The connection is working fine, but it did not download history for the earlier years, meaning my cost basis in incorrect within Quicken. When I attempt to import the downloaded QIF data into my connected account, I get an error message stating imports are only allowed for "empty accounts." It seems the account is either connected or manual. I would be happy to delete my connected account, download the full history into a new account, and then reconnect the account. Any ideas?
Any further updates?
I see no further updates. It seems I will need to use trial and error.
