Trust - Mom died May 2022, Trust became irrevocable - which option to choose in TurboTax business?

My mother died on May 14, 2022, and her living Trust became irrevocable.  I thought this would be straightforward, but I am unsure how to proceed. I am using the TurboTax Business desktop application.

 

For the section "Do You Need to Take Care of a Trust or Estate?", I don't know which option to choose, as they both seem to apply.  It is a trust, but my mother passed away.

 

    Option 1 - A trust. This will say "trust" in the title of the document.

    Option 2 - An estate.  This is for someone who passed away.  There may be a will.

 

I ran through the process using both options, and only option 2 allows me to specify my mother's date of death, so maybe that is the right option?

 

However, I am wondering if I even need to file taxes for this for 2022.  In September I liquidated all mutual funds associated with the Trust and transferred the proceeds to the Trust bank account, then distributed most of it to the Trust beneficiaries.  The liquidation resulted in a net loss of $3,400 (per the 1099-B forms received).  Since I don't have a gain of $600 or more, should I not have to file?

 

But, if I don't file, how do I generate the K1 forms for the beneficiaries to realize their portion of the loss?  Or, do I wait and file a single final tax return once the Trust is fully distributed and closed out?

 

Sorry for the long-windedness.
