Soldierswitlittlefaith, clipboard malware is very old threat and most security software will detect/block/remove such malware. Of course, hackers are constantly trying to make improved versions that are difficult to detect, so you need to make address checks before every transaction.
Hardware wallets can help with that, as each transaction must be confirmed by pressing a button before which is possible to verify that the address on the computer screen matches that of the hardware wallet device. Of course, the check should include more than 3 or 4 first/last characters, because back in 2018 there was a base of 2.3 million addresses used by hackers, and the swapped addresses can often be very similar to legitimate ones.
I think Loyce was asking why the BTC in question still hasn't appeared at that address when OP stated that the transaction has now been made.
It is possible that Hanna is decided to use a new address from Electrum, not the one originally mentioned. In any case, only she can answer that question.
