Hello Terra Seed,
Closing out your books at year end is a great way to ensure that all of the past year's work has been accounted for and you can move forward with the next fiscal year. It's important to me that you're able to complete these tasks and get going with the next stage of your books.
I know approaching these kinds of tasks can be daunting, which is why it's a great idea to have an accountant on your side. With an accountant, you'll have someone who knows the ins and outs of these processes, such as whether an account should be zeroed out or if you close the dividend account to retained earnings.
In the QuickBooks Online Community, we have a guide that can help you get started with the features in the program, but when it comes to the finer details of the accounting behind the books, an accountant is your best asset. Here's the guide I mentioned so you can take a look: Year-end guide and checklist
QuickBooks Online can also makes it easy to connect with an accountant using the My Accountant tab. If you already have someone you're working with, you can invite them as a user from that tab so they can work directly in your books. The tab also has a Find a pro to help button that links you to a directory of QuickBooks-certified accountants near you, so don't be afraid to check that out!
Have a great week. :)
