I'm using the desktop version of TurboTax for macOS. I found the problem and it's related to how once authenticates for the import.
Importing from E*Trade shows I believe 3 entries, E*Trade Bank, E*Trade Securities and E*Trade Advisor I think. I have 2FA enabled for E*Trade so connecting to E*Trade Bank with username/password+2FA works and pulls in partial trades. Authenticating to E*Trade Securities using the same approach does not work and a popup is displayed advising you to call E*Trade Support. The solution is to connect to E*Trade Securities with username/password (NO 2FA code). This pulls in the all the data.
