ITONewbie is not in the community and that is a great loss to it.

Lacerte does not directly support 8843. Create it with IRS fillable form and attach to the Lacerte 1040NR. 

So, the answer is YES. Lacerte approach to input is very different from ProSeries, but it can do everything ProSeries can do. ProConnect is very similar to Lacerte, but IMHO much clunkier and has fewer bells and whistles. This link shows comparison of the Intuit products https://accountants.intuit.com/support/en-us/help-article/compare-products/comparing-lacerte-proseri...
