I placed the PGN of the game into chat-gpt (I am using a work PC , not everything is open, please don't cook me) and it told me that I played the Smith-Morra Gambit. I didn't know the name or the line of the Gambit before this. I am usually a Rapid player so my time management in Blitz is bad. Opinions?

Can someone explain to me how is this a blunder?
