Superseded Return Didn't Supersede

Hello,

 

TT changed one of their income sections from 3 options to 2 and I selected the wrong one. Thought I was getting a refund due to new Covid tax changes. ESubmitted the return latter part of April then realized I chose the wrong option and actually owe them which I originally thought. Within an hour of Esubmitting I did a Superseded return, wrote Superseded in red on the top and mailed it in with a check. TT wouldn't allow me to resubmit the corrected return and it was too early to do an amended return.

 

My bank statement shows 8 days after submitting both returns IRS cashed my check but on the same day issued me a refund to my bank account. I thought a Superseded return was to take precedence over any prev returns. I know the refund the IRS sent needs to go back to them.

 

Will they be sending me a notice I need to send it back? Will they wait several months so I have to pay interest?

 

Any suggestions what I need to do?

 

Thanks
