I just did my 2017 taxes with turbo tax and I was wondering if my 10 year old son was added.. how do I find out ?

What software did you just use to prepare a 2017 return?  The current online software is only for 2018 returns.

i need to finish information for my son jose corona how do i do that ?

You did not answer.  Are you using desktop software that you downloaded/installed to your own computer to prepare that 2017 return?  If you are using online software right now you are making a BIG mistake.

finish on jose corona who's only 10 as of jan.24th
