My ponytail palm is sick

Hey all! My ponytail palm (Hairy Sue) seems sick. I’ve had her for 2 years. She goes outside in the spring and back in the winter. Her base seems to be caving in. I have to admit I’m not really good at taking care of my plants and she was outside through November. I brought her into the garage and just brought her into the house in December. I think she looked better then! I’ve been following my planta app directions and misting her and I fertilized her with sticks about 2 weeks ago. Watering routinely according to planta and now this. The planta app says she’s been not close enough to light. Is that correct?
