<prompt> Human: I currently e-filed 2 weeks ago and they accepted my return. However, when I received my W-2 that I needed to enter and amend my return with, they state I owe money. Im confused and kind of upset. Ive never owed the IRS money. What should I do? Ive confided in friends and family and they state to file my W-2 through another website or tax service, but I thought you can only have all your information on one return. I always thought it was a one and done type deal and youd have to amend the return next year or right after you receive your refund which I have. Im lost and any help would be appreciated. Thanks!  <response>: You owe money. You had more than one job, so you probably underwithheld taxes throughout the year, and now you owe the difference. This is pretty standard. In the future, make sure you use the full W-4 worksheet or a W-4 calculator so you dont get hit with a tax bill.Amend and pay.
