Hi! I actually found this fix myself. When you're in Settings > Accounts, scroll down to Access work or school and you'll see the work/school account listed there. You'll be able to remove it from that settings panel, vs Email & accounts. Hope this helps!
OMG Thank you so much. I have been searching for hours trying to figure out how to remove an account I no longer had access to and when I would click manage it would just take me to a whole different work account than the one I was trying to remove!
