Exact same thing is happening to me.
I purchased TurboTax deluxe 8 returns online and started my son's return, imported information from last years downloaded version without any issues.
I then started a second return for me and my wife. Imported the tt22 file for my wife and I from last years downloaded version of TurboTax and am being asked to pay $42 if I want to file the returns jointly or $21 for each return if filed separately. Haven't even really started the second return. Only just started importing the information from the 2022 return.
It appears that I can only prepare and file one return even though paid for 8 returns.
Used downloaded version for years without any issues. Only have ever filed 3 returns. No issues with the downloaded version. Real issue with doing more than one return with online version for the first time this year.
