TurboTax or IRS?

I completed my return using TurboTax; it said everything was in order and gave me the option to print it or continue to E-file.  I printed a copy, tried to continue to E-file but could not because TurboTax insisted that I upgrade to Premier because a Schedule D was required.  I checked the printed return and it included a Schedule D.  I declined this, signed the return and mailed it to IRS on March 29. It was received in Ogden on April 4 (I sent it by registered mail). I waited patiently for 6 weeks for my refund, as the IRS web page suggested, before calling.  I called the IRS today and received the same notice (from a telephone bot) as the website; saying that they could not offer me the status of my return (recieved but not accepted?). I decided that before continuing I should double check to make sure that my Schedule D was in fact correct and that I had not missed anything.  In doing so I discovered that I had erred and missed a brokerage transaction in early January of 2021.  My mistake!, and I realized I would need to file an amended return.  I returned to TurboTax to do so and upgraded to Premier status but could not continue because, while I filed on time and had appropriately upgraded, I did not know the status of me return. I am not particularly concerned (though my refund will certainly be less), but have no idea how to proceed since speaking to a real person at either the IRS or TurboTax seems virtually impossible. Anyone have any guidance other than wait to hear from IRS?
