Yup, Qe4 is the move! Qb5, exd4, Qxd5 is still checkmate! It's the only other winning move, but it's not mate in 2. There are moves like Rf8 that can avoid it. :)
Lichess because you can pick themes or openings and I believe the database they use is coming from positions in games that have been played on lichess, so you never know you might see that puzzle in a game. And free obviously.
Qe4! Threatening Qxd5#. If dxe4 d5#.
Qb4, aiming to hit d5 from the other side, just runs into exd4.

I use their database on a daily basis too!
