Get your taxes done using TurboTax

Thank you.  I have reviewed all lines.  Still not understanding why the large difference in taxes.  Can anyone explain why my taxes increased on my amendment when my AGI decreased for only $220?  One would think that since my AGI decreased  and now my Stimulus payment entered would be correctly entered, I would not owe anything additional on my amendment.  Did taxes changes in TurboTax after I filed last year in March?  This is only answer I came up with.
