It may have been because of a refund offset, meaning you owed a debt and it was taken out of your return. See reasons for offsets below: https://ttlc.intuit.com/replies/4143297 You can also contact the IRS for the remaining balance to see what the delay is. There phone number is 1-800-829-1040.
Yes, it depends on if they took all of it or some. If they took some the remaining balance is yours.
Ok. I'm just not sure what debt I owe for them to take half of my return. It was originally going to be used to pay for my balance.
Just give the IRS a call M-F from 7 a.m to 9 p.m. local time, to see what happened to your return.
