I received THREE (3) 1099-G Forms from the CA FTB for THREE (3) different Tax Yrs: 2013=$1024; 2014=$871 & 2016=$1842. How Do I determine if I have to amend my return?

I should tell you:  my 2017 Federal Return (filed using TurboTax) has already been accepted (in fact, my refund was used to pay down a previous tax year) ,,the reason the issue arose is because I received the 1009-g's on 012718...AFTERI'd already filed my federal return.
