Hi Wendy. Those 3360SC are included in a transaction on the block 135070, so it is already included in the blockchain and the funds are already in your address. You can check it on one of the available explorers here: https://explorer.siahub.info/hash/1a79a16a97247032b93643d5c35ade135b7941c9710120f9cdfbe959740133dc

- Are you using the last version of the client, v1.3.0? If you are using an older version, due to the hardfork of yesterday it will never sync up to that block (it is 70 blocks beyond the hardork point)

- Is your client fully sync with the network? As the transaction was done yesterday and blockchains sync chronologically, only the funds will show up in your balance once your client downloads that block very close to the 100% of the syncing process.
