You are correct, commuting miles to your normal workplace is not deductible. The miles you drive to a temporary workplace can be deductible. In this case, you would enter those miles as 'business' miles on the same screen where you see the box for commuting miles. There will be two different places for 'business' miles depending on the dates driven since there are two different rates for 2022.
Be aware that if you are entering these miles as an employee receiving a W-2, you will not be able to deduct these expenses on your Federal return unless you work in certain professions. Depending on your state, you may get a tax break on your state return based on the information you enter.
