How does my child file a second amendment with turbotax online

My child answered No to whether they can be claimed as a dependent on another return...so my efile was rejected. I found out my child needs to amend their return and I will have to paper file. However, my child filed the amendment but didn't actually change anything, they just selected dependent change but didn't go in and change anything. Now I believe they need to file a second amendment. When they do that TT (online version) sees there was an amendment already filed and asks if it has been filed and processed or filed and not processed. They I had them select filed not processed because it has only been accepted and TT suggests to wait until  it's processed, which from my research online can take 8 to 12 weeks which will be after Apr 15 for paper filing my return. 

 

I am not sure how to proceed. Thanks for the help
