I'm a fellow user, not a tax expert. I can tell you how to find the info, but you'll need to decide if it's correct and suits your purposes. If your specific mutual fund information you mentioned above tells you that your specific fund is 100% exempt from NY state tax for tax year 2025, then if it's 100% of the dividends allocated to THAT fund, there can't be any other states that need listing for THAT mutual fund, unless I'm not understanding your question correctly.

I don't know how your info was reported to you. If your Box 12 from a broker shows the total exempt dividends from all 3 of those funds rather than an individual 1099-DIV for each, be sure you are allocating the Box 12 dividends among the 3 funds before you use the percentage of NY exempt funds for each fund. Look for a comment I added below that gives an example about that.
I also found the percentage info for each Franklin fund.
At the Franklin mutual fund site, up near the top click "Tools and Resources."
Under Tax Center choose "Fund Specific Tax Information."
On the next page called "2025 Supplemental Tax Information", there is a search tool at the top. Enter the ticker symbol.
Then when it produces the result, do NOT click on the fund name. Instead, on that line with the fund name look off to the right and click VIEW MORE.
Then scroll down a little, and you'll see displayed "Tax-Exempt Income by Jurisdiction."
