I think your fiancé should leave the dependents section blank unless he/she has minor children. You are filing for a K1 visa which means you're not married and you wouldn't be included on his/her filed tax returns as a dependent yet.

No need to send for a new one if you already sent your application or if you already have your NOA1. They will notify you if you have rfe. Atleast you already know it’s easy fix, just prepare for your response.

Yes. If there is wrong information with your application or requirements or they need additional proof of your relationship, they will notify you. Just prepare all you think they need if you have rfe, so, you can send it to them asap.
