You do not need to convert QB's file to cvs.   It creates a .txt file which you can submit to PA - it's called EFW2 (electronic format W2).  Why it isn't called "W2 txt file" I'll never know.  Very confusing to users.

1) create file via QB Desktop (Employees/PR Tax forms/ Create state W-2 (takes you to excel). 

2) click continues /OKs until you get to the excel file.

3) Click pulldown "QB Payroll State W2" (top right corner), /  click Start Interview

4) Accept the txt file name.   Next, next / ok to end.   

5) COMPLETE!  Your W2 file was created (note below it says the name of txt file, but File Type = EFW2)

6) save to where you want as txt file.

7)  Sign into PA MyPath.   Find "Employer Annual Reconciliation" (Rev 1667) (must be included to your user to have

Click "Reconcile File Upload"   

9)  Click Attachment.   Type = PA-W2 EFW2   (not cvs)   / enter any description / Choose file - where you saved in   (6)  - usually in your documents unless you changed location.

Hope this helps someone - as it was PAINFUL to figure out..
