The custodial option of blockchain.com application that you are using does not support a cryptocurrency to fiat exchange that is why there is no way you can deposit your money back to your bank account. What you can do is to transfer an ample amount of Ethereum that is enough to make the swap from USD Digital to your preferred choice of another crypto like bitcoin possible.
After which, you can now transfer your traded cryptocurrency from your blockchain app to an exchange that supports crypto to fiat exchange such as Binance P2P or Coinbase and eventually withdraw them back to your bank account. Take note that the fiat withdrawal depends on what country you are living so it would be better to verify first what are the available fiat options before depositing your bitcoin to an exchange. The downside is, moving and swapping your crypto will cost you a few bucks due to ongoing high transaction fees.

https://www.coinbase.com/Thank you so much for your feedback. It's appreciated. I'm still not sure I'm doing this correctly. I apolagize in advance for being ignorant regarding the process. I'm concerned i'm going to do something that's going to prevent me from getting my funds back.
I've purchased the necessary ETH to trade, swap or sell my USD Digital balance. When I go to the sell prompt, I get MY GBP Wallet, My EUR Wallet and My USD Wallet. The transfer option only gives me My Exchange USD D Address and USD Digital Trading Wallet, but it has a lock icon below, so I'm assuming this isn't an option. The swap option doesn't offer a USD Digital to another form of Crypto.
When I go to settings and addresses, I have a My Bitcoin Cash Wallet and a My Bitcoin Wallet. It appears the only option I have is selling the USD Digital and sending it to one of the three GBP wallet, EUR wallet or MY USD wallet. Do any of those give me the option of transferring it to my bank acct.
I fear I didn't set up a wallet correctly.
Can you please provide direction?
