I was sendinding a litecoin payment with bitpanda and when copying and pasting it cut off last 6 digits so I retyped them but put a I instead of a 1 now I've checked that address doesn't exist and the payment is just showing as processing on bit panda with 0 confirmations will I have lost the coins? I'm assuming they won't have been sent to network as address is incorrect can anyone she's some light?
That would depend on whether or not Bitpanda checks validity of user provided address before they broadcast transaction to the network. It's actually pretty easy to do so as Litecoin addresses are encoded using base58check encoding which contains a 4-byte checksum. However, if Bitpanda doesn't do any validity checks, your funds are most likely lost. In any case, you should contact them asap.
