Bitcoin recovery

So I’m very new to bitcoin. I had purchased product from china and the product never came and the company said they would refund my money to me in bitcoin rather than PayPal which was my original payment method. So me being new to bitcoin, I downloaded the Coinbase app. They refunded my money and my Coinbase app said the funds weren’t verified and I needed to go through a recovery process to assess my funds. I did this and chose the Coinbase wallet I thought to access my bitcoin. Long story short the money was never out in my Coinbase wallet. Cainbase said they have a wallet address to where my bitcoin is but can’t tell me what wallet app this bitcoin is in. I have no clue what to do or how to access my money. Help!
