After Turbo Tax updated, Federal Refund Changed

I filed my tax in early April and got all my refund (Filed Join).  Few days ago when I login again after the latest Turbo Tax updates, saw the Federal Refund amount is now more than I got refund.   When I check the schedule 1 regarding the unemployment income, it is $20,400 instead of the previous $10,200, I believe that is what caused the Federal Refund changed to higher amount.

My question is do I need to file an amend because Turbo Tax only calculate $10,200 on my filing in early April, now Turbo Tax gave a new calculation of $20,400.  

Please advise...!

Thank you.
