I have quickbooks online app and quickbooks self employed app, which one do I use? Can I merge them? Why do I have 2?

Thanks lisa-firstbrook-, it's not possible to merge the data between these two accounts - as you're self-employed, we'd recommend that you continue with this version and cancel the online account. Both are capable of producing an Income Tax summary, so if you have a personal preference over one, you can stick with that instead. You can view details of cancelling QuickBooks Online here, and QuickBooks Self-Employed here. Get back to us below if you have any Q's!
