I can help you in locating it, chris204.
The QuickBooks Self-Employed is unable to provide you a copy of your 2019 tax return for income verification and annual stability. The program only shows your estimated taxes and taxable business profit (income minus deductions) and totals for Schedule C and healthcare deductions.
If you're using Turbo Tax, you can sign back into the account you used to file last year's taxes. Once you're in, scroll down to Your tax returns & documents (select Show if needed) then click Download/print return (PDF). For more information about this process, you can visit this guide: How do I get a copy of a return I filed this year in TurboTax Online?
Additionally, here's an article that you can read to help track the information that you'll be using to file taxes for your self-employed work at the end of the year: Get quarterly and annual tax info from QuickBooks Self-Employed.
I'll be right here to keep helping if you have any other concerns or follow-up questions. Assistance is just a post away.
