Electronic Signature Error

My tax return was mistakenly filed electronically without the electronic signature for both the federal and state return.  I was able to contact a live individual with my state and rectify the mistake there.  However, i am not able to find a solution to the Federal return for this mistake.  At this time i am unable to resend the federal form.  Question:  is there a manual procedure with a form that i can fill out, like i did with me state, to release my refund.  Currently, my federal return and refund have been in a state of 'Processing' since March of 2020.  Any and all help is appreciated.
