made a mistake on green card replacement form

Hi everyone, I made a mistake when I filed the replacement of green card 1-90 where it states to add the alien number, by one number everything else was filed correctly. Will my application be denied? If so will I have to repay the 450 dollars? If not will it delay a long time? I have to process paper work for a second job in 2 weeks and I need this job to pay back taxes and fix my vehicle.

You probably could call USCIS & ask what you should do.

Ditto, it is likely a correctable error.
