Hi, I need some advice on how I could get my Bitcoin address back.
What you have is your Bitcoin wallet, and what you need is recover your wallet to access your bitcoin.
There is nothing if you have your Bitcoin address, as you only can check it balance with Bitcoin block explorers, or import that address to have a Watch-only wallet that is unspendable.
I have an old blockchain.com wallet, in 2018 I saved the 12 secret words for it.
You have wallet seed words, so you can import it to Electrum wallet, choose BIP39.
Use Electrum wallet safely.
