My goal was to be able to transfer these funds into my PayPal account - thereby making them more convenient for me to spend...
PayPal does not support CryptoCurrency. You cannot send BTC to PayPal and then spend $$$
You would need to convert your BTC to $$$ first and then transfer the $$$ to your PayPal. To do this, you're going to need to sell them on a "fiat" exchange like Coinbase that will then allow you to withdraw your funds to a bank account etc.
Alternatively, you would need to sell them using a service like LocalBitcoins that allows you to trade directly with other people... however, trying to sell Bitcoins for "PayPal" is NEVER a good idea, as the chances of being scammed is quite high as PayPal payments are reversible... Bitcoin transactions are not. So if you send bitcoins and someone deposits to your PayPal, they can then easily reverse the PayPal payment (or pay with a stolen credit card etc)... Then you end up with no btc and no PayPal!
