Can a 90 year old widow in memory care unit of assisted living deduct care expenses from taxable income

For all of 2023 and 2024 Mom has been in a wheelchair and lived in the memory care unit of a local assisted living facility. I am POA for all things and I draw down her savings to pay ~$20K/month, at least half of which is care expenses, which are documented in the facility's care plan. I imagine her care charges are deductible, but I'm not sure
1) where within TurboTax I can make the deductions, and 
2) what documentation I need to include with her Federal Tax filing.
Thank you for your assistance.

Sincerely,
Glekou
