user134183: I have done the importprivkey as per instructions.
I can see the transactions under the transaction Tab, but I do not see my BTC under overview balance.
I do not see the address Tab also as per Wiki Instruction either.
Synchronizing with network currently on 1 year and 48 weeks behind.
All my transactions was before 2020.
Will my BTC only reflect once full Blockchain downloaded and synced with network?

user5406: The spendable funds should start being reflected in the balance whenever the transaction is processed while your node is aware of the private key. Since your wallet is already showing you the transaction, it sounds as if the key was present when the transaction was processed. I would suggest to wait for the initial synchronization to finish, during rescans and sync the wallet may still be showing outdated information until it has caught up with the chaintip.
Generally, a node will automatically rescan the blockchain after importing a key (unless you disable it explicitly, e.g. because you want to import multiple keys before rescanning once). If the key's creation date is known, it will only scan the blockchain after that date.
