Thanks for joining this thread, @Kris102.
Closing your books will lock everything entered before the closing date. If you need QuickBooks to close the year out, you have to change the dates above where it says close the books to the date of your fiscal year. To know more about this, please see this article: Close your books in QuickBooks Online.
Also, to guide you in completing your year-end tasks in QuickBooks, here's the article you can open: QuickBooks Online year-end guide and checklist.
Feel free to post here anytime you have concerns about closing your books in QBO. I will be happy to assist you. Have a good one.
