How can I review schedule e before I file

The only really good way to review Schedule E is to print it out and look it over. You can review what you have entered so far, or delete it:

1. Sign in to your TurboTax account.
2. Open or continue your return.
3. Select the Menu icon in the upper right side of the screen.
4. Select Federal from the left menu.
5. Select Rental Properties and Royalties (Sch E). 
6. Continue through the next two screens.
7. On the screen called Rental and Royalty Summary, select the ellipsis (three dots) next to the property that you want to review or delete.
