Hi I don't even know if I am posting in the correct area. I just really need some help right now.
I downloaded Bitcoin Knots and I clicked file > receiving addresses > new > then had the money sent to that address. I then went on youtube and saw people doing it completely different (ie. they were getting their address from the receive tab, whereas I got mine from the file tab in the top left corner). Have I just wasted all my money?
No, that's how I do it in Bitcoin Core. If Knots is anything like core, you should first see an incoming unconfirmed transaction. This transaction should eventually get confirmed depending on the fee.
