IT in large is a very broad spectrum so getting in to "IT" has a lot of paths. Do you want to be a developer? Work on Leetcode's and whatever language you want to work in. Sys/Dev ops? Get familiar with cloud architecture and SaaS/IaaS/etc. platforms and get related certifications. The list goes on and on. Just getting in to "IT" is not a practical approach.
