After much trial and error finally solved the problem.
Close and restart TurboTax.
Make sure the data for the first Fidelity account is there.
Identify your default browser that TurboTax will open to import data from the second account .
Clear all cookies AND cache…..clearing cookies alone will not work.
Input the login information for the second Fidelity account when TurboTax asks.
This should work.
