Bitcoin in wallet transactions but not on the blockchain (old wallet) I've been checking old wallets and found an unconfirmed transaction that's on the wallet but not on the blockchain
transaction id (missing from blockchain)

My wallet showing a transaction

How do I access these BTC and get them onto the blockchain? I could be wrong but I believe that it's such an old unconfirmed transaction that it doesn't even show on the blockchain.
So far I have tried forcing the transaction to go through again with a hex code of the transaction on https://blockchain.info/pushtx, but it didn't work
Please help! It's a long shot but the amount of BTC is huge, so I want to try every approach at accessing the BTC before giving up.
I'm afraid you won't be able to access these funds.

The transaction is not, and has never been, confirmed on chain. From the perspective of the network, it doesn't exist.

If that doesn't work, it likely means the transaction is spending funds that no longer exist (i.e., it was double spent). The error you get from sendrawtransaction does not mean anything, as your node is not fully synchronized yet.
Regardless, I'd suggest to let your node synchronize with the network. It's possible that it has received other transactions at that time, which did get confirmed.
