If there are any boxes with zero, please leave
those blank in TurboTax.
If you have entered a 0, please backspace
over it and be sure there are no number, decimal points or characters in those
fields. If most of the lines across are
the same, you can use the blue copy previous month button to enter it
again.
If
that does not resolve the message, this TurboTax FAQ has information about this
message in Form 1095-A, a work around and a click-for-email-notification link,
at the bottom.
