How do I find out my taxable income for 2019? This NY form is asking me for my taxable income for 2019. I don't if they want federal or state? And what is "IT-203-X"?

IT-201-X or IT-203-X  are the NY state tax forms for amended returns.

The state of New York will want to know your NY taxable income.

Some states use your federal taxable income and then do additions and subtractions.
