For a 1099-B assigned to the wrong family member tax IDN, how do I input the explanatory information into TurboTax on why it was added to one and removed from the other?

The Investment Firm will correct the tax IDN for 2024, but will not retroactively change the 2023 1099-B issued.  

At the heart of the issue is a Trust account where the Trustee's IDN was incorrectly used instead of the Grantor's IDN when a new account was established within the Investment Firm.  Given that, can it be handled through the "I need to adjust the dividends" option within TurboTax?  The guidance language is "You received the dividend as a nominee: You are a nominee if you receive dividend income that actually belongs to someone else (other than your spouse). Remember you must inform both the IRS and the person you received the dividends for of the payer and the amount."  The Dividends and Capital Gains do belong to someone else.  The "Learn More" selection in the "Tell us about your dividend adjustment" indicates "TurboTax assumes you want to adjust the total income from dividends and capital gain distributions reported on your 1099-DIV by the dividend adjustment amount you enter. If that is NOT how you want to handle this adjustment, select Back, adjust the amount of each separate income item, and uncheck the adjustment choice. Be sure to attach a statement to your return explaining each adjusted amount."  The challenge is the three examples of making changes that reduce the percentage of 1A and 2A combined, but don't eliminate the incorrect dividends and gains.  So, how does one properly adjust each separate income item (Boxes 1A, 1B, 2A, and 5) for the received 1099-DIV?  I can make each entry zero, but how do I attach an explanation statement?
