1099 NEC related deductions

[SdTTUser18]

My wife works as a part time physical therapist in adult day care center. She received 1099-NEC from this facility. She also works part time in another outpatient health care facility which issued W2 for her. TurboTax generated schedule C considering 1099-NEC as personal business income.  She had to buy liability insurance which can be deducted on schedule C. What other expenses can she deduct? Can she deduct car expenses? Or would it be considered as commute from home to adult day care center and hence cannot be deducted?

Mileage from home to her place of work and back home is commuting and not deductible. Business use of a phone, licensing and continuing education expenses are deductible.
