I would recommend that you walk through the Amendment process in TurboTax just to make sure that the interest reported on your Form 1099-INT doesn't affect your return.
The 2018 Form 1040-X is estimated to be available February 14, 2019. You SHOULD NOT make any changes on
your return in TurboTax until this form becomes available.
