When using TurboTax Online, you will be able to view forms that apply to your situation once you get to the 'File' section. In the Free product, you will need to review and confirm your info. Otherwise, you will need to complete payment at this stage.
After that, you will have access to File > Print Your Tax Return, where you can download a PDF copy of your return. You do not need to be finished to access this PDF.
Once you are finished, remember to come back and generate another PDF reflecting the final version of your return for your records.
