Thanks so much for answering me...since I posted my question I found a couple of things:
1. My monthly premium was indeed $617.24 per month
2. There was a document from NYS Marketplace that lists the amount of the "Second Lowest Silver Plan" for my county to be the same $617.24
3. Column C - reads as zero - not sure if there is anything I need to change there.
I did not receive any advance payment of premium tax credit.
Thank you.
