I'm trying to redeem a 9 year old Casascius bitcoin using Electrum 4.1.5 and the wallet menu only has sweep as an option. When I try to use p2pkh:PRIVATE KEY syntax, the sweep button does not enable to click sweep. Most documentation from previous versions of Electrum had an option to import private keys and later to sweep...


Is the p2pkh:PRIVATE Key entered in just string like - phpkh:XXXXXXXXXXXXXXXXXXXXX
OR
phpkh:
XXXXX
XXXXXX
XXXXXX
XXXXX

Newbie here, any help would be grateful
thanks
