Hi All:
I already filed the 2018 tax return, but recently I got the SSN for one of my child (she used ITIN before), I want to use the SSN instead of ITIN, so that I can get the Child Tax Credit, because I got the SSN this year, so not sure if it can be used for 2018 tax return, and if I need to file the amend for 2018 tax return. Appreciate if anyone can help.
