SNAP after a layoff: what documents did you send? after 15 years as a copywriter

I got a notice asking for proof of income and I am unsure what to send. I have read a lot of threads here and could not find my exact situation. I have a final pay stub, a termination letter and my unemployment approval. Did they ask for anything unexpected?

Ask about expedited service. I was told it depends on how little cash and income you have right now.
