If you omitted income, overstated withholding and paid in taxes or dependents, or something different affected your filed and accepted federal return, as long as IRS is finished processing it, then you now need to file an amended return to include the missed unemployment income.
Hopefully you can e-file it so it can be processed faster. Be prepared to pay back some of the original refund received in case your taxable income is increased on the amended return.
Here are some instructions on "How to Amend your federal return":
First, make sure you really need to amend and that your 2020 return was accepted in TurboTax Online or paper-filed through the mail. You can't amend a return that hasn't been filed yet.
