The payroll company that manages our company's payroll messed up and sent two separate W2 forms. I already filed one thinking this was my total return, how do I fix this?

The company sent one return having only March-December on it. I thought my pay looked low on the W2, but I didn't think anything of it. Well a week later, the payroll company came forward and said they made a mistake and sent us which did not include January-February on the W2. I already filed and actually already got my refund, so how do I go about filing the other part my W2 (same company)?

Since your return was accepted by the IRS, you'll have to amend your income tax return(s) to add the additional W-2 form.  

However, the IRS has not finalized the 1040X amendment form. They're scheduled to issue that form around February 14, 2019. When they do issue the form, see How to amend (change or correct) a return you already filed.
