The substitute 1099-R won't work either. You can't leave Payer's ID number blank or input random numbers. You'll get an error which would prevent e-filing.
If you report a foreign pension as Other Income on 1040, you' won't get NY state pension exclusion, because it won't be listed as pension. You can get those exclusion only when you pay federal tax.
The state form can't be manually changed or adjusted without creating errors. Returns with errors can't be e-filed.
Turbo Tax could provide a worksheet or manual adjustment for state tax filers so they can report this part of other federal income as foreign pension (if they can's solve the issue with Payer's FIN on federal 1099-R forms). This would solve the problem.
