I received a 1099-K form in error as my mom did not know how to use Venmo and clicked on purchases when sending me money. Do I still have to report this?

Yes, but there is an option to report that this amount shouldn't be included.

1. Navigate to Federal > Wages & Income
2. Choose 1099-K under Other Common Income
3. Enter the information from the 1099-K
4. Check the box that says, This amount in box 1a is too high or includes some personal transactions
5. Enter the amount that shouldn't be included
