Transfer of 2023 tax data (from desktop Turbo version) to Turbotax 2024 Online

I have a MAC computer. I did my 2023 taxes on the desktop version of Turbotax Premier. This year I used the online Premium version of Turbotax for my 2024 taxes. 

As advised by TT assistant, I went to TOOLS and then downloaded a 2023 .x tax file. I then hit transfer. After a brief period of time only 2 of my 7 dividend accounts from 2023 were transferred! I made many attempts-- same problem and then the seeming transfer took over 10 minutes and was still going. The TT assistant aborted this before it completed. 

This is being escalated as a technical problem. But I am dubious given past experience. 

Is there possibly a work-around for this issue? it seems I saw one online, but can't find it. 

Thanks! 

P.S. There was no listing below for the Premium version I am currently using, so I was forced to choose Premier.
