we have 2 firms/efins for our Lacerte package. One of our Intuit account lists our firm's EFIN correctly, but the downloaded/installed preparer file for that firm contains the duplicate EFIN of our primary firm, yet all the other information is correct, address, contact, etc.  This firm/efin has been used since 2016, and is correct in all our prior year Lacerte modules.  Any other time we've had issues with the detail in the prep files, we've contacted support, they made the changes, and then provided a corrected prep file to download and apply.  but this time Lacerte support advised the only way to correct our data file was to upload our IRS approval letter again to get the preparer file updated.  I was on the phone for over an hour, and I'm wondering if any of you know a more 'direct' method of resolving this simple request to them.  Thank you in advance.
