I am a GA resident who has NY State non-resident income. Under "NY Additions Allocation," "Changes to Federal Income, Non-resident and Part year Resident Adjustment Allocations" TurboTax lists "Interest Income on State or Local Bonds" -$3946. I have not idea where it comes up with this number. Probably some percentage of bond fund investments. Similarly, under "NY Subtraction Allocation" it lists $432. Do I minimize the impact of both of these for the NY allocation ("0" for the $3946, and the entire $432 for this subtraction)?
Yes, if your only New York income was the wages or other New York state income, you would want to not include the Interest or allocation amount.
Do I need to manually allocate Federal income to the different states ("additions/subtractions"), or does TurboTax do this automatically? I prepared the two non-resident state returns first, before the one for my resident state.
