After you file

My Employer deposited the $300, My Employer owes $1000. My Employer did not fix the prior year and I need to Ammend because My Employer deposited my 2024 in 2023. Nothing was Direct Deposited this year to file. My Employer is not fixing the Situation I emailed Turbotax Compliance Daniel Oseran but no reply. I am supposed to have until the 15th.
