Windows 2024 Delux Fed+State won't let me save

[ftkungnj]

I bought the 2024 Delux  Fed+State at Costco today. Downloaded and installed it on my Windows laptop. Transferred 2023 data into it. Finished some personal data stuff. Before I start to enter data I tried to save the file. It just wouldn't let me save, kept saying the file did not exist. Tried to change file name, use "save", or "save as", none worked. I had to exit without saving. Now I have to restart and transfer 2023 again. I don't know how I should proceed at this point.
