"This Return Has Already Been Submitted" and Non Filers
Hello,
I keep getting the notification "This return has already been submitted" from the Free File Fillable Forms website when I try to submit my 1040.
I used the Non Filers website earlier this year to procure the stimulus check.
Am I receiving the notification because I used the Non Filers tool to receive the stimulus?
Is filing a paper return my only option?
