<prompt> Human: At the beginning of the year, I worked part-time at lowes. I made 4,530.31 in wages and paid 267.06 in federal income tax I live in Florida, so I have no state taxes. When I submit my w2, at the top of Turbo Tax it says FEDERAL REFUND: 267. I have a 2nd w2 from my current job. So I was curious to see how much I would get just from that one so I deleted the lowes w2 and added my current job. My wages were 21,422.51 and my tax withheld was 1,732.68, which makes my new FEDERAL REFUND: 581. My question is: why is it that when I add both of them together, my refund drops to 166?  <response>: I wrote a long post about the Why did my refund drop when I entered a second W-2? question here:
