I am a good backwards skater (I figure skates before hockey) as a defenseman. However, I cannot take a slap shot to save my life! I suck. Whenever I take one the puck just flips. I workout a lot on upper body strength... I can’t figure out the problem!! Help!!!

I’ve only been playing for two years

So there are hundreds of free instructional videos available online from reputable coaches, but you ask for advice here?
No wonder you suck.

Is this comment really necessary? Probably just a kid trying to get better. Very rude and immature. Get lost
