The IRS began to send out the additional refund checks for tax withheld from unemployment in May. The refunds are being sent out in batches—starting with the simplest returns first. 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.

How do I know I’m eligible for it ?
From the IRS website that was posted in the reply by @xmasbaby0 - https://www.irs.gov/newsroom/2020-unemployment-compensation-exclusion-faqs-topic-a-eligibility
You're eligible to exclude the unemployment compensation if it was received in 2020 and your modified adjusted gross income (AGI) is less than $150,000. The modified AGI for purposes of qualifying for this exclusion is your adjusted gross income for 2020 minus the total unemployment compensation you received. This threshold stays the same for all filing statuses, regardless of whether you're married and file a joint tax return (it doesn't double to $300,000).
