You will have file file an amended return to enter the unemployment and taxes withheld. Please wait until your original return has been processed and see How to amend a tax return to get a refund on the taxes paid (if you qualify for the unemployment exclusion).
If your modified adjusted gross income (MAGI) is less than $150,000, then you can exclude up to $10,200 of unemployment compensation paid in 2020 from your taxable income. Amounts over $10,200 for each individual are still taxable.
