My wife called the IRS this week to check on our 2017 tax refund. IRS reported that we were refunded approximately $2500 on 5 April 2017. Where is it?

Where was it supposed to go?  To your bank or to a broker account?  Did you have any fees deducted from your refund?  

One poster found this.....

The refund was sent to a bank I didn't recognize because Schwab where I have an account uses an intermediary bank, JP Morgan. So the refund was in my Schwab account which has little activity and I had not checked. I had not had a refund in so long, I did not remember the default account I had set up years ago for refunds.

Did you mean they sent it April 2018?  April 5, 2017 would be for a 2016 or earlier refund.
