I would restrict myself to asking questions, and helping with parts she can't do herself, but only at her direction and request.

They can be planning questions: What will you do with this research when you have enough information? Will you make a way to show that research to someone? Who should see it? But I wouldn't make any suggestions about what format the next steps should take. Let her own it completely.

I would lean more toward giving tools than toward doing it for her, always. Especially if she is struggling in other areas, let her own the output of her work.

Does she have a writing disability, and if so, is school accommodating appropriately?
