Deductions & credits

I prepared my sister's taxes and had included her unemployment income. We have not filed it yet. I've reviewed everything and there's nothing in TurboTax that calculated the $10,200 deduction. I have the Desktop version, not the online version. The TurboTax FAQs seem to imply that one should file first and THEN TurboTax will guide you through the steps to get the deduction. Am I missing something? 

 

"If you haven't filed your 2020 tax return, yet, go ahead and do so. TurboTax will guide you through claiming these additional unemployment benefits."
