Can see imported calendar items on iPhone not on PC iCloud

My Google business account was made inactive last year by Google. I didn't mind, as my business closed a few years ago, and I assumed that since my calendar was still active it must be attached to a personal Google account. When I wished to print off a copy of my Google calendar (as it appears on my iPhone 16), I learned that I couldn't do it from my phone. I logged into iCloud on my PC, but my Google calendar doesn't appear anywhere. I have read articles about how to import it, but they only show how to import it to my phone. The problem is that my Google calendar is already on my phone. I have used Google calendar as my main calendar for many years and make changes to it only using the native calendar app on my iPhone.I paid the Google minimum subscription to regain access to my calendar, but that doesn't seem to help. How can this be done? Please help!
