If you have paid $2,927.08 in federal taxes, and it says you owe $2,275, that means you underpaid your federal taxes this year by $2,275. In other words, you should have paid $5,202 in federal taxes this year, but only had $2,927.08 withheld.
Since I don't know your entire tax situation and how many deductions/credits, etc. you may have, these numbers may not be entirely accurate. I'm just basing it on the information you provided above.
