Move the "make a comment" box to the top of comments instead of below?

Not easy for people to add a comment when they have to scroll to below all comments. lmk how to adjust theme so it moves the comments box to above them.
Sample page with comments: https://agentrosehq.com/m-zero-oneshot/

Also checking the mobile version of this page on Google Page SPeed insights shows that it's extrememly slow on mobile but doing well on desktop. Lmk if there's anything I can do, because I don't use too many plugins and can't really get rid of any at this point.
