My Form 8949, section Undetermined

Question #1: Turbo Tax gave me 3 errors, requesting that I must provide Date Acquired for all 3 items. I requested the Acquired Date from my broker and they replied: “These are principal payments from UIT allocation events. These are payments made to the account that are 1099-B reportable but are not directly tied to the cost basis to the position. They are paid out based off the quantity held for the position at the time of payment and we do not supply either and open date or a cost basis allocation on these payments.” 

What is your advice? How do I report these?

Question #2: Turbo Tax gave me error: The Date Sold of item 3) is 1/7/26 which falls out of tax year 2026. My broker’s answer: “the 01/07/2026 payment date is the day the fund paid out the principal allocation, but they indicated it is tax reportable for Tax Year 2025.”  Please advise how to report this.

Thank you so much!

Question 1: The date acquired is the date you purchased the original security the UIT allocations were tied to. 

Note: This could become complicated if you had additional purchases throughout the taxable year, before or after various "allocation events".

Question 2: If the cash was paid on January 7th but it is realized and includable for Tax Year 2025, then use 12/31/2025 as the date of sale.

Hi MelindaS1, 

I know the Date Acquired is the Purchase Date but my broker did not provide that the Acquired Date. They said "These are payments made to the account that are 1099-B reportable but are not directly tied to the cost basis to the position. They are paid out based off the quantity held for the position at the time of payment and we do not supply either and open date or a cost basis allocation on these payments. "  

I am not happy about that so I had to go back to my statements and look for the Acquired Date.

Thank you for your prompt reply and your help.
