When using the TurboTax online editions you do not have direct access to any forms, schedules or worksheets
You can view your Form 1040 at any time using the online editions. Click on Tax Tools on the left side of the online program screen. Click on Tools. Click on View Tax Summary. Click on Preview my 1040 on the left side of the screen.
If you want to view/print/download the complete tax return you will need to pay for the TurboTax online account.
To pay the TurboTax online account fees by credit card, without completing the 2021 return at this time, click on Tax Tools on the left side of the online program screen. Then click on Print Center. Then click on Print, save or preview this year's return. On the next page, to pay by credit card, click Pay Now. The next screen will show a review of your Fees, click on Continue. Complete the next screen to pay by credit card and click Continue.
Sorry---you are using online software and you do not have direct access to the forms. Forms mode is a feature of desktop software. You have to enter your information by going through the interviews and screens. You can only peek at your 1040.
