State tax filing

Please help, I already submitted the NYS and it gave the exclusion of 20,000 which I dont think I am entitled too. This is not a gov or NYS pension.  Now the submission is pending with only two days left to file. How can I amend and fix it.  Incidentally I also did a test on Turbo Tax and when I entered NO to not review it automatically put the exclusion as well. I had to go in and say yes to review then take the 20,000 out.  

Are all seniors over a specific age entitled to this exclusion?  Its bizarre this is happening.
