Dear community, how do I print out Schedule E before I file it. I need to check the numbers.

You have to pay the TurboTax account fees to view or print your complete tax return.

To pay the TurboTax online account fees by credit card, without completing the 2020 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.

Will I be able to change my tax return after I pay the fee? Some information on my tax return does not make sense to me

Yes you can go back in and change anything you want.  You might have to click on Add A State to let you back into your return.  Do not click on Amend!
