Here's how to enter "other income" in TurboTax so that it will be reported on Schedule 1 line 8z with a description that you enter. However, as noted in the answers to your other post of the same question, this is not the correct way to enter foreign interest or capital gain. In particular, if you enter the capital gain this way it will be treated as ordinary income, not capital gain, and you will not get the lower tax rates for long-term capital gain.
- Click the Federal Taxes tab.
- Click Wages & Income.
- Click "I'll choose what I work on."
- On the screen "Your 2021 Income Summary," scroll all the way down to the last section, "Less Common Income." Click the Start or Update button for the last topic, "Miscellaneous Income, 1099-A, 1099-C."
- On the next screen, "Let's Work on Any Miscellaneous Income," scroll down and click the Start or Update button for the last topic, "Other reportable income."
- The next screen asks, "Any Other Taxable Income?" Click Yes.
- On the next screen, "Other Taxable Income," enter a short description such as "Foreign capital gain" 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.
