I ran into the same problem, coming from H&R Block after they wouldn't fix a SW bug on their side. I couldn't import from our 2023 return until I re-opened H&RBlock 2023 and printed an abridged set of 2023 tax docs. I didn't print all of the worksheets, and left out schedule E. This was then readable by TT2024, so I got a bit of my info read in automatically. That said, it interpreted our 2023 AGI without a decimal point, thus multiplying it by 100 (that'll probably haunt me when I go to efile - will need to catch it). Be sure to verify all imported info!
