Searching my MacBook Air, both with Spotlight and with the old-style Finder search with both visible and invisible items requested turns up no .sty files at all, and only .cls files I'd installed for a journal my last paper went to.  The manuscript giving trouble is using the amsart document class, but I can find no corresponding .cls file on my machine.

TeXworks is just a frontend: (La)TeX itself is provided by your TeX
system, almost certainly MacTeX in your case. As such, your question is
really one for a general TeX list.

The core MacTeX files live inside /usr/local/texlive/<year>/texmf-dist
and are easiest found via the Terminal, something like

  kpsewhich amsart.cls

to find the amsart class. (Packages end .sty, classes .cls.)

That said, amsart is a very common class so it seems unlikely arXiv has
no version available. Do you get a .log file from arXiv: it might give
more of a clue as to which files you may need to upload.
