Thank you ... my question is a purely technical one. Each correction changed something else; only the items that changed are reflected on the corrected W2. I know what the "entire" picture looks like.  

My question is .... do I enter all W2s as a single W2 and check the box that it is a corrected W2, or do I need to enter all three documents separately. I am pretty sure the first can be the only correct answer, but I see nowhere in ProSeries help documentation that this is the case, or whether there may be other steps.

Also, the latest W2c provided the OK state employer number, left off the previous correction and the original. There is a "?" in the employer number(!) This is surely an error, right? I am waiting for a reply from the wage accountant .... but I'd love someone to confirm this ....
