After you file

I fully concur with the "adjustment should have been made by this time" (and should, indeed, be made as soon as practicable) but, unfortunately, it does not appear to be anywhere close to a top priority. 

 

With respect to support, it would also be nice if there were some sort of "advanced" level with personnel who had the requisite knowledge. Unfortunately, that is highly unlikely to happen since people working in that department would need to be familiar not only with an 1120-S, but also with 1120s, 1041s, and 1065s.
