I am 65 years old, and have COPD. I cannot cut my grass because of this, and pay a service do this. Is this something that can be deducted as a medical expense, and if so, where/what form?

No, paying to have your grass cut would be considered a personal expense and is not deductible on your return.  

Thanks Annette.  Thought that might be a stretch, but figured I would ask anyway.
