Hi there makenna,
It's vital that all your transactions be correctly entered so that your sales accounts are balanced. QuickBooks Online is a great tool able to help you keep track of sales and expenses made by your company to see your profits. I can point you in the right direction for assistance with your sales.
In order to know how you should be entering your sales, as well as how to best correct the sales already in the system so that your books are correctly balanced, I recommend speaking to your accounting professional. They'll be able to analyze the transactions you made in the system with you in order to show you how you should be keeping track of those transactions. You can add your accountant or bookkeeper by navigating to the My accountant tab. You can also find an accountant near you by clicking on the Find a pro to help button in that section.
If you have any other questions, feel free to reach out here.
