IT-203 new york state returns discrepancy in total capital gains in federal and state amount

I recently filed my returns for Federal and State taxes for CT and NY (part year resident). They were accepted but I realized that there was discrepancy in total capital gain between Federal and New York State amount in New York State returns. In particular, my New York part-year resident income tax return (IT-203) shows that my New York Capital gain amount (Line 7) is much higher than Federal amount (16k vs 8k). My total capital gain from investments was only 8k. So I am not sure why the New York amount is stated higher. Because of this I must be overpaying New York Taxes. How can I fix this? As far as I know, I uploaded all documents (W2, 1099-Int, Div, and 8949 from Robinhood) correctly. Did anyone run into similar issue? Any input is highly appreciated.
