I am a Jessie - But here to tell you this...
https://wallet.matic.network/bridge
Here is the bridge. Be at Eth Network at metamask and depost Eth with this bridge.
Then you will see it here https://wallet.matic.network/ (if you are connected with metamask)
And you can swap here https://quickswap.exchange/#/swap
Looks like this. remember to at right network in metamask.
Just tell me if you need a better guide.
