At the moment, QuickBooks Self-Employed (QBSE) does not have a feature to generate a balance sheet. The software is designed to assist you in tracking business transactions and estimating federal taxes. It helps you make quarterly tax payments and complete your Schedule C for your annual tax return (1040).
For more details, check out this article: QBSE Overview.
I'd also suggest visiting this website: Self-Employed Individuals Tax Center. This link provides more information about tax obligations for self-employed individuals like you.
In case you're a business owner and you send more than 10 invoices monthly, you'll want to consider other QuickBooks products.
