How to add previous payroll to aquare for end of the year W2

[HootHoot]

We have been using square for timecards since the beginning of the year and had a CPA do payroll.  In June we dropped the CPA and have been using Square for timecards as well as payroll.  How do I add the first 6 months of payroll information so that my employee's W2 will be correct.  

All of the clock-in, clock-out info is already in there for the first six months, but not "payroll/paid" info.

OR will I have to give them 2 W2's?  That seems very unprofessional.

Thanks in advance.

Have you called Square yet?  I can only speak to my experience, but when I switched to Square payroll, they requested all of the information from my previous provider so they could make sure that all of the numbers matched with the government.  I would give Square a call on this one.
