How to calculate outside tax basis for Final Schedule K-1 (form 1065)?

I have received a Final Schedule K1 (Form 1065) from my employer and it says "You should calculate your own outside tax basis of your partnership interest to determine if there is any additional gain/loss upon disposition of your interest"

 

Do you know how this can be done on Turbo Tax? Or do you think I should seek in-person help from a tax advisor?
