Using Desktop version. How do I access forms for an additional return?

Yes, you can start a new tax return in TurboTax Desktop by selecting Start a New Return in the lower left of the first page, or by selecting File, then New Tax Return in the upper left corner of any page. 

Once you select that, you can select a 2022 tax file to bring forward, or you can start form scratch by selecting Continue without transferring in the lower right corner. 

if you are asking how to use forms mose. go to the view tab and select forms. be careful there are both the actual forms and worksheets. the data must be entered in the worksheets and not the actual forms. using the actual forms will require mailing and void the accuracy guarantee.
