I'd like to amend my 2019 taxes as my son gave me his 1098T. I had claimed my son as a dependent even though he's 26 but I considered him a qualifying relative because he earned less than $3000. I'd like to amend now because he gave me his 1098T which I can use to receive a better refund. The problem is that it gives him him an additional $5400. in "income" as he received a grant (box 5). Can I still consider him as a qualifying relative because he "earned"that much more or does it depend on real earnings and not income from a 1098T?
