Hello,
Passive investment income is taxed to the resident state unless it's clearly source income like rental property in that other state.
You will need to file 2 State returns.
1. File a non resident return reporting the investment income ( as long as it's sourced in this state)
2. File you resident state return
Make sure you complete the nonresident state first and TurboTax will figure out and give you credit for taxes paid to the nonresident state on your resident return.
