After you file

My 2023 e-file return has been rejected 3 times, error says spouse AGI doesn't match IRS records.  We had the same AGI and it was correct on e-file, but the error only mentions spouse and not me - why?  Due to natural disaster extensions I believe my paper 2022 return hasn't been fully processed by the IRS yet.  I'm going to try the AGI zero trick, how many times can you try to re-file an e-file return before getting locked out by the IRS?
