If you earned income from money that you invested, you must report that income on your tax return.
It sounds like you are looking at a sample of Form 1099-MISC. That is not the type of form used for reporting investment earnings. The form issued by Acorns should be either a Form 1099-INT or a Form 1099-DIV, depending on whether your earnings took the form of interest or dividends.
Once you determine the type of income you received, open your tax return in TurboTax, search on "1099-INT" or "1099-DIV" and you will be directed to the correct input screen for your earnings information.
