You must make the indications to TurboTax that this is Other Income. Edit the Form 1099-MISC, indicate that non of the uncommon situations apply, indicate that it did not involve work like your main job, indicate that you got it only in 2018 and indicate that it did not involve the intent to earn money.
If this doesn't work, delete the Form 1099-MISC and reenter it manually.
(Presumably his was resolved long ago since the question was posted 4 months ago.)
