You already put yourself in a situation where you could have lost your bitcoin by not making multiple backups of your seed phrase. Luckily, everything worked out in the end.

If you are going to continue to use your Electrum wallet, ensure that you back up your seed now. Don't put yourself in the same situation twice. After you open Electrum and unlock your wallet with your password, click on Wallet>Seed. Enter your password again and the software will display your seed. Back it up physically on multiple pieces of paper or metal. In the future, that seed is all you need (plus the Electrum software) to regain access to your funds. You don't have to go on a search for wallet files on your drive. The same is true for any other non-custodial wallet.
