Hi sunshine20231,
Welcome to the Community. It's important to correctly record your transactions to keep your books balanced. QuickBooks Online is a great program that gives you the ability to easily track your sales and expenses. I'd be glad to help.
I encourage you to reach out to an accountant. They'll be able to point you in the right direction to calculate and pay the taxes to keep your books balanced. If you don't have an accountant, you can find one near you by clicking on My Accountant on the left navigation menu> and then Find a pro to help.
Let me know if you have questions, I'll be happy to help.
