Here's how to enter "other income" in the 2022 desktop TurboTax software so that it will be reported on Schedule 1 line 8z with a description that you enter.
In the Search box in TurboTax type "executor fees" (without the quotes), then click the link that says "Jump to executor fees." That might not be what the income was, but it's the best search term I could find that gets you to the right place.
The first screen asks, "Any Other Taxable Income?" Click Yes.
On the next screen, "Other Taxable Income," enter a short description and enter the amount. Click Continue.
On the next screen click Done.
You will get a couple more screens with unrelated questions. If they don't apply to you, just answer No and click Continue.
You have clicked a link to a site outside of the TurboTax Community. By clicking "Continue", you will leave the Community and be taken to that site instead.
