You can purchase QuickBooks Self-Employed (QBSE) by going to this page: https://quickbooks.intuit.com/self-employed/pricing/. There you have an option to choose a plan that will fit your way as a freelancer.
QBSE will help you you track your business-related transactions and calculates your federal-estimated taxes. Having it aids you to make quarterly estimated tax payments and file your Schedule C with your annual tax return (1040). For more details, check out this article: QBSE Overview.
I'd also recommend checking this website to know more information about the tax obligations for self-employed individuals.: Self-Employed Individuals Tax Center.
