Unfortunately I don't know in which wallet you receive the 110 USDT fee so to send it to the exchange you have to pay a fee of $20. 
If the wallet you are using can use the TRC20 network you should be able to send your assets for a very small fee, so you can convert them to Fiat and you can use them for your needs. 
Try opening your wallet again and looking for an address that uses the TRC20 network!
