Yes, you can check the status of a split refund using the Where My Refund? feature available on IRS.gov or by calling IRS' Refund Hotline at 1-800-829-1954. Where's My Refund? will include a message confirming that your refund was split. It will not specify the amount deposited into each account, but it will tell you the estimated date of the deposits and, if IRS adjusted the amount of your refund for math errors, etc., will tell you the amount of the adjustment.
