Final Living Trust return creating sub-trusts

We have a main living trust made irrevocable by the death of the grantor in 2012.  In 2022, the trust was distributed equally to 3 sub-trusts to hold the assets for later distribution to beneficiaries upon their reaching a certain age.  The assets are appreciated stock held in 3 brokerage accounts under the sub-trusts EINs.  There was also a small distribution made to one of the beneficiaries from the main trust.  

How do I report the distributions in TurboTax business such that it closes the main trust and allocated the ownership to the sub-trusts?  There are no carryforwards from 2021.
