Yes, the Deluxe desktop version does import from TXF Files that are not for ESPP sales. The information you see here https://ttlc.intuit.com/questions/1899278 regarding Premier and Home & Business is specifically for those importing "capital gains" since Premier or higher is recommended for entering that information when you use desktop software. But Premier or higher is required for capital gain entry when using TurboTax Online software.
If you go to import capital gains information into Deluxe, it'll prompt you to upgrade to Premier for additional guidance but you can choose to continue in Deluxe version.
