State tax filing

I sold a rental property in 2020 in NY.  After completing the appropriate forms, there was a loss of $6,223.  I see this amount listed on Schedule NJ-Bus-2 line 12 which states Loss Carryforward to tax year 2021.  As I do not want to leave anything on the table, Can someone please tell me if this amount is eligible to claim on my 2021 taxes and if yes, how and where tp do it?
