CA state tax return Schedule S: State postal code - California nonresident cannot claim other state tax credit

Hi,

I moved from New York to California in October 2025 and became a part-year resident of California starting at that time. However, I continued to earn salary from New York during October–December 2025.

Since this income was taxed by New York, I attempted to claim the Other State Tax Credit on my California return to avoid double taxation. However, the Smart Check generated the following error:

“Schedule S: State postal code – California nonresident cannot claim other state tax credit...”

As a result, I am unable to e-file my return.

Could you please advise on how to resolve this issue? Thank you.
