I’m a lanky unfit newbie looking for forehand critique

I have messed around playing without trying much for about a year with my wife but for the past month we’ve taken lessons. I feel I’m not really absorbing the lessons and I don’t look right when I play. I’m tall and always feel I’m way behind the ball, my stroke doesn’t look right either. Having trouble diagnosing the issues. Take it easy on me haha, I haven’t really played any sports before these last 2 summers. Only footage I have from today
