Unfortunately, you would have to contact
the Connecticut Department of Revenue Services for an explanation of why they are reviewing your return. They also won't show an amount for "refund" until they have completed the review.
State Departments of
Revenue and Taxation (and the IRS) select returns for additional review using a
number of criteria, one of which is completely at random. They often review e-filed
returns if there are large refunds due because of W-2 withholding; employers
are not required to send the state its copy of the Form W-2 until Jan 31, so
the state doesn't have independent verification of the withholding you are
reporting.

Depending on the reason
for the review and internal policies, they may not tell you why your
state return was selected for review.
