Federal filing got rejected due to dependents

I screwed up something, pl. help. My situatuation is this.

 

- My daughter is a full time student in Missouri in 2023

- I paid her tuition of $60K for the whole year

- But for boarding and lodging she has taken student loan, but it is about 25K or so.

- She does not have any income

- I had been filing her return all these years and did so this year already though she may not need to file since income is 0.

- But I think I entered her as a dependent in my return. So mine got rejected.

 

To correct this ... this is what I am planning to do ...

- Do not show her as a dependent in my return

- And cough up an additional $500/- due to this mistake. I am OK with this.

- Refile just mine

This looked easier than filing an amendment for my daughter's return. 

Is this OK?

 

Secondly, I live in Arizona and I kept my daughter's permanent address as AZ only. So I filed her AZ return, and not Missouri. I had been doing this in the last couple of years too. Is this too OK? OR does she need to file Missouri also?
