My Federal Tax due is showing -$197,858 which is an error because a property was not sold but exchanged (1031). I tried to erase Form 4797 unsuccessfully.

You'll need to go in and correct the information you previously entered.

To edit your Section 1031 information TurboTax Online:

1. If you don’t see 2022 TAXES in the left pane, select the dropdown to the right of Income & Expenses on the Hi, let’s keep working on your taxes! page and then select Let’s get started, Pick up where you left off, or Review/Edit. 
   • Otherwise, in the left pane, select Federal, then Wages & Income (This is labelled Income & Expenses in TurboTax Self-Employed)
2. Scroll down and select the Show more dropdown to the right of Other Business Situations
3. Select  Revisit to the right of Sale of Business Property
4. On the  Any Other Property Sales? screen, you most likely have the Any additional like-kind exchanges (section 1031) box checked
   • Unchecking the box won't change what you've input.       Leave the box checked and select Continue
5. On the  Like-Kind Exchanges screen, select Edit to the right of your exchange item
6. From here, you can correct any information previously entered.
