I'm getting asked to enter a "date placed in service" for my vehicle but I only use it to commute to and from work, so not sure if I should be entering this.

You should not enter information about your vehicle if you only used it for commuting. Commuting expenses between your home and your main workplace are never deductible, even if you have a long drive or haul work supplies during your commute.

A few states let you deduct some commuter expenses, but that is done on the state tax return. 

Please see the FAQ below for more information.

Can I deduct commuting expenses like gas, mileage, or toll fees?  https://ttlc.intuit.com/replies/3300445
