In the 2020 interview this was very hard to find. I almost forgot to deduct our $10000 --- since the place to enter it is under INCOME that Connecticut treats differently! It's a deduction, not income! Even when I remembered that I should deduct it, I had to come here to see where TT asked me about (after wasting a lot of time searching for it under deductions). This should be fixed.
