So, I’ve tried “free” withdraw from a pool…

Hello guys!So – I know nothing about crypto and today It hit me hard and now I need Your help.I'm a Ethermine.org miner and few days ago, after last payout i've decided to try L2.I made a InfinityWallet to be able to connect with Ethermine (nad use l2 i think?)Today I received crypto from pool and tried to send it to my Coinbase account.How surprised I was when I get error that I don't have enough Matic to send it.Ok, I'l just buy it a coinbase and send it…WRONG! After buying Matic and sending it to my InfinityWallet address I saw this:

I guess that Coinbase have send this via ethernium mainnet. I found that I can use some bridge to transfer Matic, but well.. gas is way above value of this ETH.
What should I do guys to put those ETH on mine PayPal? I guess Coinbase is out with this " Coinbase supports Polygon (MATIC) transactions via the Ethereum network. Sending transactions via Polygon (MATIC) main-net will result in the loss of funds. "
