I put in my first W2 and was at a refund of 890, but when I put in my second one it dropped to 575? Did I mess up?

Every time you add income, the refund amount will drop (the more money you make, the more taxes you owe-the smaller the refund will be) until you get to the credits and deductions sections.

Nope....that commonly happens...you could even have ended up owing more and no refund.

Depends on what your total withholding was from ALLL your income forms.    The withholding is only an estimated prepayment of taxes. 

Your first W-2 entered may have used up all of your Std Deduction, and when you entered the second one, most, or all of  that income ended up being taxed.....or even maybe pushed the added income into a higher tax bracket .....that wasn't fully covering the tax withholding that was done.
