Out of curiosity, I went looking.
Instead of entering $9364, I think you should enter only $154 (the taxable amount). Even though it was taxable on the federal return, CT does not tax it. So there is an INCOME adjustment (subtraction) on line 49 of form CT1040 (line 49 is a catch all line for several "other" items).
From the instructions for line 49 of form CT1040:
"5. Subtract the amount of any distributions you received
from the CHET fund as a designated beneficiary to the
extent includible in your federal adjusted gross income."
