Windows 10: How do I remove my high school portal from my MacBook to login other accounts?

I'm trying to log in to my personal Gmail account, but it keeps directing me to my school login portal. It has been this way for a couple of months now, and I don't know how to remove it because it doesn't give me any "setting" section. I decided to figure out a way out of it because today I was completing a mini course for my university and I had to log in through my email but it brought me to my high school portal which didn't let me access the videos for my mini-course.I've tried looking through my MacBook settings using a couple of methods I've seen on Google, but they're outdated, which l

Remove Deactivated Work Or School Email Account

I have an organizational email account that has been deactivated, current guides online say the following:

"If you need to remove an account from your PC:

1. Select Start > Settings > Accounts > Access work or school .
   
2. Select the account you wish to remove, then select Disconnect
   
   ...."
   

However, the only option presented at this section is "Manage" which forwards me to my organization's page to login. The account has since been deactivated with no way to get to the next step.
I have been getting notifications from my system that "There is a problem with a work or school account click her to fix now" but obviously can't login to remove the account from the system.
Is there a work around to remove the account without logging in?

 

Removing school account on Microsoft

Hi, so I have tried removing one of my school accounts through the settings app, and the school account that I want to remove isn't even there. When I go to settings and search "access work or school" only my current school account shows up. I am a transfer student and so I no longer need my previous school's account. What's weird is that my previous school account doesn't show up when I search it up in settings. I have been trying to use google drive and google calendar and it leads me to my previous schools account login, however that account isn't listed on my school/work accounts. I have been trying to log in to google drive and google calender on my personal account, but both links always lead me to my previous schools log in, but I don't have access to that account anymore either. I am not sure how to remove a school account that isn't even listed on my school accounts in my settings. There is no way for me to get out of the log in page for when I click the links for either google calendar or google drive.

To delete an account, follow these steps:

1. Press WIN + X keys and click Command Prompt (Admin) from the menu.
2. Type the following command and press Enter. Replace test with the name of your sister's account. Code:
