Does anyone know how you can track the Federal unemployment tax return after you already filed and received your tax refund prior to the bill passing?

There is no way to track the refund from the IRS for the unemployment compensation exclusion.

Go to this IRS website for information - https://www.irs.gov/newsroom/irs-begins-correcting-tax-returns-for-unemployment-compensation-income-exclusion-periodic-payments-to-be-made-may-through-summer

Just be aware that these refunds will continue to be issued throughout the Summer.
