I am a non-resident (NJ) filer with income from NY and am funding our kids' 529 plans under the NY 529 plan (deduction code S-103 on the IT-225). In years past (when not efiling), I have been able to allocate the 10,000 deduction against NY income, but Turbotax is not allowing this when trying attempting to efile. I believe I should be able to allocate the deduction against NY income, but TT won't allow this or an override to efile. I may just end up mailing in the return if it's not something that can be fixed.
