How did you enter it as a W2? Did you get a 1099NEC for it? Do you need to enter expenses? After you delete the W2 entry, add it on Schedule C. Is this your first time with self employment income? I have more info on that.
How to enter income from Self Employment

Actually I would just enter your total income as Other self employment income or as Cash or General income. You don't need to get a 1099NEC or 1099Misc or 1099K. Even if you did you can enter all your income as Cash. Only the total goes to schedule C.
