I had an NFT in my eth wallet then bridged across to BSC and the transaction cost transaction came through but the transfer of the NFT did not produce a transaction so it is still sitting in my ETH wallet. Any idea how to correct this?
Hello!
Alex from Koinly here 
At the moment we don’t have NFT support, but we’re working on it and it’s almost done!
We were hoping to have it out before end of last year but we got a bit delayed.
I can’t guarantee any release date but it’s looking like sooner rather than later! 
For now you can follow this guide to manually enter the NFT transactions:

And then you would just need to create a “Transfer” transaction for the NFT placeholder token you used with the BSC and ETH wallets involved.
Sorry for the inconvenience!
Best regards,
Alex
