I found out on my 2017 return that my child dependant's capital gains income that I included on my return was taking away so.e tax credits I should have been eligible for. I want to amend my 2015 and 2016 returns to remove her income and file her 2015 and 2016 returns seperately. Will she have to pay penalties and interest even though I overpaid? Also what order should I do this in?
