I don't know for sure. I don't do Fiduciary returns, but I would check the "Tools" menu>"Import/Export Data" submenu to see if that gives you anything.

If it doesn't, I'd recommend setting up Microsoft Power Automate to do it for you. Wesley Hartman taught a class on how to use Power Automate with Lacerte that's recorded in the paid accountant's community AutomationTown.  I'll let you google for the link.  Highly recommend.  Disclaimer: I get no kickback if you sign up for Automation Town.
