When will TurboTax 2018 process the $7,500 credit from Form 8936 worksheet through Form 8936 to Schedule 3?

I have filled out Form 8936 Wks in TurboTax 2018 Home and Business, but it has not carried through Form 8936 and found its way onto Schedule 3. I can't afford to file my tax return without this $7,500 credit.
