Rcvd 1099-DIV late ($36 ord div/$16 qual div/$43 cap gain distrib). Amended my return with no other changes. Why was adj gross income $146 more when only $95 was added?

Got the 1099-DIV from Vanguard late (2 weeks after I eFiled). So now I did an amended return with TurboTax Premium. When done, TurboTax did it's thing and summed it up as $146 net change for my adjusted gross income.  That is about $50 more than the added income entered on the 1099-DIV that I received late. Shouldn't the numbers match?
