Why does my total federal refund go down in amount after adding my second W-2?

[romeron1375]

I went from a $1600 return to a $190 return, I thought adding both W-2s from the job's I have worked would have add both amounts together, not bring one down?

the second w-2 increases your taxable income which increases your taxes and the additional withholding on the w-2 is insufficient to cover the increase in taxes.

The amount of your refund depends on how much was withheld from your paycheck.   So if there was too little withheld from your paycheck during the year, your refund is decreased.
