Check if the address is correct, probably you sent to the wrong address if no confirmation on blockchain.com wallet. If the address is correct, then it would be good to import your seed phrase on another wallet like Electrum to recover your fund.
On Electrum GUI, click on file -> new/restore -> name you wallet and click 'next' -> standard wallet -> I already have a seed -> choose a derivation path -> create a password. Your wallet will sychronize with the blockchain and your balance should appear.
