?? ProConnect or Pro Series???

If ProConnect, the only thing I can think of is you clicked one of the headings at the top or maybe a different year. I fully expect it is operator error. 

My question was related specifically to the Proconnect program.  

When I go to Proconnect, I can see the clients I prepared in Proconnect-(my business clients) BUT I can also see my 1040 clients that I prepare in Proseries Basic.  I also have just a couple of business clients I have used Proseries to prepare their returns, but I cannot see those business clients listed in Proconnect, ie the business clients in Proseries.

So a better question is-Why, when I open Proconnect, I can see my 1040 clients listed in Proseries Basic, but I can't see the clients in Proseries? 

The reason being is that I'd like to prepare, in Proconnect, the business clients I used Proseries in the past.  

You are asking a community of other users. This sounds to me like some of your ProSeries clients were not converted. Contact support and they can help you.
