Hi marilynsouthwell.
Being able to enter your business taxes paid in the right account is crucial to keep everything correct and up to date. I'd be happy to help point you in the right direction to get this entered.
When it comes to where to enter your business taxes from prior years I recommend reaching out to your accountant as they are trained in how to make these entries. If you don't have an accountant no worries. You can find one in your area by going to My Accountant>Find a pro to help.
Once your accountant tells you how to enter it or what needs to be entered where let us know and we'd be happy to help guide you how to do it in QuickBooks Online.
