The IRS controls the tax refunds for the unemployment compensation exclusion and they will not inform you if you are going to receive a refund.

The extra refunds for tax on unemployment started in May, but they will be sent out from May onward throughout the summer. Be patient. There is no way to track when or if you will be receiving it.
If you are eligible for the extra refund for federal tax that was withheld from your unemployment the IRS will be sending you an additional refund sometime during the next several months. TurboTax cannot track or predict when it will be sent. The IRS has not provided a way for you to track it, so all you can do is wait for the refund to arrive.
