how to do add in tax benefits from working from home for my wife and I ?

What do you mean by   "tax benefits from working from home?"

Are you W-2 employees who work from home?

W-2 employees cannot deduct job-related expenses on a federal return.  Job-related expenses were eliminated as a federal deduction for W-2 employees by the tax laws that changed for 2018 and beyond.  Your state tax laws might be different in AL, AR, CA, HI, MN, NY or PA.

If you live in a state that lets you deduct job-related expenses, the information will flow from your federal return  to the state return, so enter it in Federal>Deductions and Credits>Employment Expenses>Job-Related Expenses

Or are you running a business from your home?  Are you self-employed?
