Retirement tax questions

I'm just confused because on the CA Refund Page under "Transportation and Commuter Benefits" it says to “Enter the amount of employer-provided transportation or ride-sharing benefits received and included in federal income.”

I got $100 per month pre-tax while I was employed there (8 months out of last year). So I just don’t know if I am supposed to enter in how much my commuter benefit amount was or not. It was $800 and if I enter it, it adjusts my CA refund by $1,600....which seems like too much so I don’t want to do it wrong.

The amount is NOT listed on my W-2 but IS listed as both a credit and debit each pay period. So I don't know how to treat it.
