CT Tax return

My only income is a pension and an Annuity....I am 57 years old

 

Why on my CT state tax return for 2022 is line 4 blank???I

I seem to be getting back all of the state income tax that was withheld from my Annuity??? Why is that annuity not being taxed by the state of CT? or have i entered something wrong??? This has never happened in previous years...The annuity is always taxed 

 

Example...last year I had $3120 withheld from the annuity..the amount I should have had was $1261.00...so my refund was only $1859.00..But in 2022 my refund is the full $3120.00
