After you file

it usually takes the IRS 6-8 weeks to process a paper return. Due to the recent government shutdown from 10/1 to 11/12, processing could have been delayed. However, it's also possible that the IRS never got your return. Until it's processed the IRS doesn't even know if it has it.  You could try calling but as stated the agent won't know unless it's been processed. your other option is to send in a second copy with the notice and a letter of explanation, signed and dated,  that a joint return was previously mailed but that your spouse got a notice of non-filing so are submitting a copy. Hopefully you didn't owe.    

 

is the notice for 2024 since the IRS usually doesn't send them out that soon after the filing deadline?
