Filed taxes using 1040 joint form and now April 16th received a K-1(541). Capital loss carryover of $800. Do I have to amend my return and file this?

K-1 is on deceased dads living trust.

You should have both a 1041 K-1 (federal) and a 541 K-1(CA state).

Yes, you should amend your federal and state returns to include the K-1 form.  Note that amended returns need to be printed and mailed as they cannot be e-filed.  See the instructions for creating an amended return in TurboTax below:
