This looks like something I replied to a while ago at https://proconnect.intuit.com/community/lacerte-tax-discussions/discussion/how-do-i-import-accountin...

Unfortunately Intuit, in it's infinite wisdom killed all of the old likes and didn't link the new ones to the old. 

I think most of what you want can be found at https://proconnect.intuit.com/community/federal-taxes/help/lacerte-trial-balance-utility-faq/00/5974

I am sure @IntuitBettyJo will get her team to try to fix the broken links in my last article.
