After you file

I had to mail my 2019 Return in July when turbo tax couldn't get the electronic return to go through. so I printed off the "mail my return" option which gave me the address to send it to and I mailed my return and my payment together. The check went through my account, but now the SBA is saying that my 2019 return has never been filed with the IRS. 

 

I went into my account on the IRS website and there is a letter from the IRS confirming that they never got my return. Where do I go from here? Obviously Turbo Tax gave me the wrong address or something?
