My return was rejected- IRS was still processing my 2019 return, AGI changed. I filed an extension. Logged in to fix it, now says E-File Accepted- is that the extension?

I haven't gotten a confirmation email that the return was accepted and no refund yet, though Turbotax said it should have arrived a month ago. The IRS refund check tool shows nothing- just says to recheck the entered information. There's no longer an option to "fix my return" on Turbo Tax. Is is actually accepted?
