Unless the trust chose to pay the taxes on the taxable portion of these distributions, which usually doesn't make sense, you should receive a Schedule K-1 (Form 1041) from the trust reporting the taxable amount of these distributions that is to be reported on your tax return for the year that contains the end-date of the period in which this distribution to the trust occurred. Given that the distribution from the IRAs occurred in early 2021, there's a good chance that that would mean receiving the Schedule K-1 for reporting on your 2021 tax return, but if the trust uses a fiscal tax year that ends early in the year, it could be 2022 income to you instead. So what you need to find out is if the trust is paying the income taxes or if the trust is going to issue Schedule's K-1 to the beneficiaries for the beneficiaries to pay the taxes. The casual note should have already included this information for the beneficiaries' tax planning purposes.
