Need help with stuck transaction

I have a small ETH transaction that I was sending from my CB wallet address to my regular CB account address. The total of the transaction was only about $25 and the gas/transaction fee was going to be about $20 so I wanted to see if I could send it for less and adjusted the transaction fee amount.
Bad idea…it’s been “pending” since October 29th (almost 4 weeks).
I tried signing in with MetaMask and canceling it using a technique someone on YouTube posted about. That didn’t work.
Anyone have any ideas on how to fix this, cancel it, or how to increase the amount spent on gas? Thanks!
