If you have deposited tokens onto the Injective Chain, the funds may not be visible until the network has confirmed this transaction (the transaction is still on its way). Typically, transfers between Ethereum and Injective Chain can take up to 10 minutes, while transfers between IBC compatible chains (CosmosHub and Terra) and Injective Chain can take up to 2 minutes.
It is also worth checking whether the funds have left the source chain (i.e. where you are sending the tokens from) as you may not have paid the sufficient gas fees to support this transaction.
