Actually....this morning I tried one more time to compare our 2016 Lacete data paths entered vs. what it says in our 2021 Lacerte data path.  I could have sworn that before the 2021 Lacerte data path involved the sdata path.  Now it says idata path....so I changed the 2016 data path to idata and VOILA!!!! The clients are now listed!!!! Will try this on 2017 & 2018.  Wish me luck! 🙂  Thank you again for your reply.  Sometimes the most simple solutions are the best ones!!
