How do I verify if I will get the amended tax return for unemployment?

[Critter-3]

If you have already filed  before the change then  the IRS will recalculate your return for the new unemployment exemption for you automatically. There is no need for taxpayers to file an amended return unless the calculations make the taxpayer newly eligible for additional federal credits and deductions not already included on the original tax return.

Just keep waiting. The IRS is sending them out in batches over the summer.
