Did you code the SIT to NY?  If you did, PTO will flow the number correctly to both IT-2 and IT-201.

To e-file the state return with SIT, you'll also need to fill out at least the State and State EIN under Electronic Filing (W-2 State/Local).

If this is an outbound assignee and it's a not repatriate year, my question would be whether you have considered breaking NY state tax residency at least during the assignment period even though a bit of low level planning may be necessary.
