TurboTax can't import 1099 from multiple accounts in Fidelity

[AJ2023]

Got a problem with TurboTax when a user was importing Fidelity (FD) data to TurboTax:

FD: two brokerage accounts (A & B) under one ID/PSWD

Problem: TT can import 1099-B(-r, -Inv) from only (and always) one account (for example, a combination of 1099-b for account A, and 1099-inv & 1099-r for account B. And there's no way to add the second one. (1099-b/inv/r expected for both accounts).

Tried both online and desktop and failed.

Does each Fidelity account have a different set of login credentials?

No; the two accounts are with the same login credentials.
