Idenity verification

I will filled out and e-filed my 2024 taxes March 4th 2025 and then received a notice for Idenity Verification and sent that in the middle of March.   I am still waiting for my refund?  It has been long and the status says they are processing the refund  , but nothing else?  What else or how long will this process take place?  It has been almost four months already?

Thank You very much
