Confused about a document

Retirement 2024 Taxes.jpg

I have this document that was sent to me by my retirement board, as I am a retired firefighter.  The letter states I am eligible to deduct an amount by editing form 16b of the form 1040, but in Turbo Tax, that doesn't seem possible.  Can someone help me get pointed in the right direction???  Thank you in advance
