My inclination would be that you stop paying for things that are specifically her choice: phone, subscription services, clothes, shoes, toiletries, travel, holidays, alcohol etc.
You continue to put a roof over her head, cover the utilities, put food in her belly at mealtimes. Do not ask her to stump up for the overall household pot at this stage or in the coming years as a student.
In the meantime she absolutely should help out with general household chores and jobs. Whether that's only what affects her directly (her laundry, her bedroom, her meals that aren't shared with you) or all the shared work: dishwasher/washing up, hoovering, dusting, bathrooms, gardening, bins etc, well that's what you'll need to discuss and negotiate. Good luck 🤞🏻
If she continues to live with you after university, with a full time job, then would be the time to discuss a financial contribution.
Does/did her father contribute or pay maintenance? Has that stopped? Is it going directly to her? I'm assuming DP is not her father.
