Hello, How can I find out if I'm eligible for the unemployment tax return/refund?

You are eligible for the unemployment exclusion if you received unemployment benefits in 2020 and your Adjusted Gross Income (AGI), not including the unemployment, is less than $150,000.

If you have not filed your tax return yet, you will get the exclusion on your tax return when you file. It will appear as a negative amount on Schedule 1 line 8. If you already filed, you might or might not have gotten the exclusion on the tax return that you filed. If you got it, it would appear as a negative amount on Schedule 1 line 8. If you did not get it on the tax return that you filed, the IRS will recalculate your tax return and send you the additional refund. It might take several months to get it. For details see the following IRS announcements.
