After return was accepted

Hello,

Need help, I did a return on my taxes, and it was accepted within an hour. So today I tried to check the return on my desktop for confirmation of the acceptance by IRS, and when I checked, it states that I didn’t e-file yet.

I decided to go ahead and e-file again, and I when I did, I received a pop-up stating the following:

 

’The submission is a duplicate of one that was previously received. please contact customer support’.

please help, and thank you for your assistance
