How do I know which products are in small and light?

I’m trying to ramp up sending our products in to FBA and have dabbled over the years but I’m sure this may be a stupid question but how do I know which items have been enrolled in small and light? A few years ago someone from Amazon enrolled lots for me but it’s not clear from inventory page if it’s normal FBA or small and light - is there s report I can pull off with Small and light? I’m happy with the process of adding inventory to FBA and then enrolling into S&L but it’s the existing ones I’m confused about
Thanks in advance!
