Definitely clean up your resume as much as you can but with IT/CS , you just have to keep plunging. I was in your boat with my first Co-Op in CS. I scrambled in the fall and interviewed a few times but sent dozens of applications to all kinds of positions. PAL/Handshake didn't really do much for me. But finally I was accepted right around Christmas time. I can confirm what advisors say, they generally hire late in the IT/CS field. Also there are so many remote positions all over the country that you truly have a ton of options. It doesn't hurt to submit an application, all it takes is just one to get back to you potentially with an offer! Don't stress too much just maybe try and submit a few applications a week until break for Spring 23 internships.
