filed taxes for 2020 by mail march 2021. subsequent turbo tax updates lower the amount I owe

my mailed return in March 2021 showed I owed 16204.00

After Turbo tax updates my tax liability has been significantly reduced. Should I send an amended return?

Also should I send a check for just the updated lower amount turbo tax now claims I owe?

no information on my return changed it seems as though a new tax credit was issued by the feds that lowers my tax bill
