This whole donation thing smells fishy.
But anyways, try pamodlar's suggestion but install
android version of electrum instead if your PC doesn't have a webcam.
In the wallet creation process (
import prv keys/addresses).
When prompted to input private keys, use the "
camera icon" just below the input box and scan the QR code.
After a successful
scamscan, if the output starts with "
1, 3 or bc1" it's an address and the donator is a scammer;
if it starts with "
5, K or L" that's a private key,
create a new wallet and sweep it instead so others wont be able to spend it (
fingers crossed that it's a private key).
