This is NOT correct answer. If you look at your IT-203 PAGE1-2, the Smart Worksheet is adding (IT-203,line 19 plus IT558) . It added $10200 back to the NYS Gross income. Therefore, you needed excluded $10200 from line 16-other income. The NYS Gross income line 19 should show the total excluding $10200. Line19A is taking the NYS income from the "SMART Worksheet" which included $10200.
Simple math, line 31 NY Ajusted Gross income should show your income from NYS source.
