Hi there, @scatterplot,
Right now, we're unable to create a TXF file format in QuickBooks Desktop for Mac. Please check out to this article for supported file extension in your account: File extensions used in QuickBooks Desktop.
As another workaround, you can pull up your file through extracting and importing reports to Excel. Then, you can look for an online converter to help you with the file format needed for importing your file.
You can also visit this site if you have other related topics about QuickBooks Desktop for Mac. This includes guides and the latest news about the software: https://qblittlesquare.com/.
Stay in touch if you have follow-up questions about importing data. I'm here anytime you need help.
To my knowledge Quicken was the only Intuit product that generated a .txt file. TurboTax works with QB Windows as long as both products are installed on the same computer, TurboTax extracts the data from the QB Windows working file. To date TurboTax has yet to produce a product that will extract data from QB Mac.
As mentioned by my colleague above, we're not able to create a .txt file for your QuickBooks Desktop data. Let me provide additional details about this.
As of the moment, there are only a few file types which can be created from your QuickBooks Desktop for Mac. These include:
In the meantime, you may follow the workaround given above to export your data to TurboTax.
Fill me in if you have other questions. I'll be sure to get back to you.
