Are you referring to the new tax law (American Rescue Plan Act, aka ARPA) from earlier this Spring with the "up to" $10,200 unemployment income exclusion? If you filed prior to that new law, the IRS has been busy recalculating people's returns to provide any additional refund due. The process will continue through the summer. They worked on the simplest returns first. Unfortunately, no one in a user community forum can tell you anything specific about when you would get yours.

"The IRS plans to issue the next set of refunds in mid-June. The review of returns and processing corrections will continue during the summer as the IRS continues to review the simplest returns and then turns to more complex returns."
"Taxpayers will receive letters from the IRS, generally within 30 days of the adjustment, informing them of what kind of adjustment was made (such as refund, payment of IRS debt payment or payment offset for other authorized debts) and the amount of the adjustment."
