TT is in transition from 2018 to 2019. while in transition only forms and schedules required for filing can be printed. you'll have to wait until the conversion is finished to print your full return including worksheets not required for filing.
Having dependents does not necessarily add any pages to your tax return. Your dependents are listed on the first page of Form 1040. No additional pages are needed just for the fact of having dependents.
Plus this year the federal forms have major changes. Everything goes on a little Form 1040 that has six extra "schedules" with it.
The new 1040 is 2 half pages but now print on 1 sheet with the Signature line in the Middle.
IRS Schedules 1 thru 6 (only if needed)
