Multiple Pending Transactions

I’ve had around 20 pending and queued transactions for a few months now. I was experimenting with the wallet trying to get really slow (cheaper) transactions to push through but they will not. How can I clear all of them? I don’t want to reset the wallet as I fear I’ll miss out on airdrops but I can’t push any transactions out while these transactions are pending.

I’ve tried the +1 nonce from my last successful transaction but it still won’t clear out the transactions.

If I reset the wallet will I lose out on the monies I already have staked or will they recognize my wallet address? I’ve experimented around entering my seed phrase as well and it doesn’t seem to be working so I feel like if I reset my account I’ll lose everything I have staked.

Any help would be appreciated. Thanks in advance.
