What do I do if my return has been accepted, refund issued, but taxes on unemployment received were taken out but shouldn't have been?

Using TT Home and Business desktop. My refund has been issued, but now when I go into TurboTax for that return it's saying my refund should have been larger from IRS and CT, and it's probably because I received unemployment money last year and filed before the IRS said the first 10,200 of unemployment is not to be taxed. What do I do now??
