If you sent it , it should be there… You cannot send from one chain to the next in Metamask… You should be able to add the Harmony address to Metamask and see the token.
If you add this to Metamask and switch to the ETH chain, you should see the tokens… You might need to add the 1ONE eth contract to Metamask which is 0xd5cd84d6f044abe314ee7e414d37cae8773ef9d3
After that, you can use bridge.harmony.one to bridge the ONE tokens to the Harmony chain if you require.
