My mother died on March 17th 2026.

1 - do I need to file her taxes?

2 - I took in my 4 siblings. aged 15, 13, 11, 11. I have legal guardianship. I am aware I can claim them as dependants next year but am I able to do that on this year's taxes? I have not filed yet.

Update - i am aware of survivor benefits. Im already in the process of handling that.
