It is now illegal for ebay to pay you , unless it is to a verified bank account via managed payments.

Depending on how long the money has been on hold, it may be no longer held by ebay / adyen, could now be held by ASIC

You will not be given any payment to your PayPal account. eBay moved to Managed Payments two years ago.

That means you have to sign up to Managed Payments, and verify both your ID and your bank account, in order to receive those moneys. Have you tried to verify your bank account via eBay's preferred method? Alternatively, you can verify the bank account via the micro payments method.

Quoting from eBay:

I understand it can be stressful and annoying, particularly for occasional sellers rather than those operating as a business.

Have you looked through eBay's Managed payment help pages? This one (Updating your bank account details for payouts) and this one (Registering as a seller - specifically the Verifying your banking details section) are both of use in cases like yours. Even if you've sold items previously, under eBay's MP (Managed Payments) you'll be classed as a new seller if you've not been consistently selling enough items under MP, and also if you're not already fully verified (ID and bank account) for MP.
