TXF worked well for me.
Before I input a large amount of data like this TXF file into TurboTax, I like to take a look at it to see if there are any errors in the data.
I was converting TXF file from Quicken into an XLSX file (EXCEL). I was concerned initially because I saw only the headings, but no data.
Then I clicked on the EXCEL icon again to launch EXCEL again, and voila! There it was,data and all.
