How to report distributions of principal from a Trust

Our mother had a revocable trust.   It included several rental properties and a mutual fund.  When she passed away in 2022 her revocable trust became an irrevocable trust.  We (my sister and I both sole trustees and beneficiaries) sold all the properties and now want to distribute all assets and close out the trust.  The trust did earn any income after becoming irrevocable.  I am using the Business & Trusts version of TurboTax but cannot see where to report the principal distributions or even enter in the starting assets.
