How do I know if I should be expecting taxes on the 10,200 in UC I paid had fed & state taken out. WI resident HOH 1 Dependent. WI isn’t refunding state ik that! ?

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.
