I have a1099-Int which shows amounts for 2 account numbers - one for a saving and one for closed CD. Turbo Tax is only picking up on the 1st amount listed.

You may have used the electronic / auto retrieve feature for TurboTax. Consider manual entry for the missing / second account number.

If you are relegated to entering both account numbers manually, make sure to delete the electronic / auto retrieve entry, so as to not double report the same account number.

Yes, all interest from all forms must be listed. You can add it manually or you can clear cache and cookies, and try to import the second form. Always view your tax forms for accuracy before filing.
