Please explain to me the unemployment adjustment that’s supposed to be made on everybody taxes or those who paid taxes on their unemployment???

If you have unemployment you can exclude up to 10,200 for each person if your income is under $150,000.  Your unemployment compensation will be on Schedule 1 line 7.  The exclusion will be on Schedule 1 Line 8 as a negative number. The result flows to Form 1040 Line 8.

If you have filed early before the exclusion, the IRS will recalculate your return for the new 10,200 unemployment exemption for you. 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.
