Rejected return

I fie taxes for my mother in law who is 94.  I filed her 2022 taxes and they were accepted.

Last year (2023) I filed them and they were rejected.  Unfortunately I use her phone and email on the form and so did not see wither the rejection or code.   I did not realize this til I was in the process of preparing this year's taxes.

She owes nothing and would receive back less that $100 so I was not concerned and thought I could file them after the 2024 taxes.

I did his years taxes for her and as last year. TurboTax indicated no errors.  

I used my phone number this year as her contact and got a rejection notice again.  Since I did not have access to her email I went on the program and selected the last item on the pull down menu which is filing status.

I hit "fix my return" and it indicated I had to correct her last year AGI.  As it indicated in the directions since there was no last year return I entered 0.

When that popped up I changed it to 0.00 and it indicated I should resubmit.  Now I'm waiting to see if it net through.

Is there anything else I can do?

If rejected I will file for an extension and submit late I guess.

Thanks
