Locked USDT in Ethereum Mainnet

Hello guys,

By playing with forces I do not understand, I ended up locking $500 USDT on Metamask Ethereum Mainnet.
All I was trying to do is fund my Metamask account trough Pankace Swap with ETH so I can purchase some coins, but I only accomplished having $500 USD Thether on my Ethereum Mainnet account.
I want to take them back to Binance, but in instead of charging me $25 fee, like on the way in, now it wants $180 fee or more, to transfer the currency back.
What options do I have to taking my money in a place, where I can use them, with minimal fees?
Thank you
