@Anonymous - let me answer the easy part first
1) only the medical expenses that exceed 7.5% of your income is eligible for itemization. So look at Line 11 (AGI). the first 7.5% of that number gets subtracted from yoru total medical expenses.
2) Further, do you have enough expenses to itemize at all? If you are filing Single, the standard deduction is $12,200 for 2019 (add $1650 if you were 65 years old or older in 2019). if you don't have this level of expense in total (medical or otherwise), forget tallying up all the medical expense and just take the standard deduction.
3) For Room and Board, you can deduct the cost of meals and lodging at a hospital or similar institution if you’re there to receive medical care. In other settings, you can deduct the cost of lodging ($50 per day maximum) while away from home if you meet all of the following requirements:
- The lodging is primarily for and essential to medical care
- The medical care is provided by a doctor in a licensed medical care facility
- The lodging isn’t lavish or extravagant under the circumstances
- The stay isn’t for personal pleasure, recreation, or vacation
